INTRODUCTION
This booklet records the text and illustrations of the lecture given on Thursday, April 7, 2011 at Rydges Hotel in Canberra during “The Centenary of the Spirit of Ecstasy Rally” of the Rolls-Royce Owners’ Club of Australia.
The Rally Director, Ian Irwin, asked me to display and discuss the Spirit of Ecstasy mascots I have collected since the formation of our club on June 6, 1956. Back then, I owned a Rolls-Royce 20 H.P. GDK35 but it did not have a mascot. George Green, a fellow foundation member of the RROCA, allowed me to copy his kneeling Silver Dawn mascot. I used dental duplication jelly to make a wax pattern which was then cast in brass. I later learned that this was the technique used by the creator of the original ‘Spirit of Ecstasy’, Charles Sykes. He made the mascots and sold them to Rolls-Royce Limited from 1911 to 1928. His daughter Josephine (Jo) Phillips (nee Sykes) took his place from 1928 to 1939. The mascots were, over this period, always an optional extra and recorded as such on the sales cards.
In 1957 we sold our 20H.P. and left for overseas. After six months in the U.K, we moved to Rochester, N.Y. where I was to undertake post-graduate study. Before our departure from Australia, our club appointed me a vice-president so I could liaise with the U.K.’s 20-Ghost Club and the Rolls-Royce Owners’ Club of America. This official status was very helpful, as we were made Honorary Members of the 20-Ghost Club and, later, we were made most welcome in the U.S.A. by John McFarlane, inaugural editor of the RROC Inc. journal ‘The Flying Lady’. He and his Advertising Editor, John Utz, both lived in Rochester. The U.K. and the U.S. experiences provided me with many opportunities to learn more about the mascot.
In 1960 John McFarlane asked me to write an article on the mascot for ‘The Flying Lady’. He arranged for R-R Ltd to supply photographs from the mascot collection of Stanley Sears’, the 20-Ghost Club President. He also obtained the hand-written lecture notes used by Jo Phillips for her lecture about the mascot to the UK’s Rolls-Royce Enthusiasts’ Club in December, 1959. My article appeared in TFL pp. 502-506, July 1961. I up-dated and extended this article in Praeclarum 2-07 to 5-07 and in ‘The Flying Lady’ 07-2 to 07-3. It can be found at rroc.org.au in the ‘General Library’ section.
I have been able to continue my mascot studies through the kindness of many colleagues, who have, over the years, allowed me to copy their interesting or unusual mascots on the basis of one for them and one for my collection. In the meantime, these owners can use the copy mascot on their cars and leave the original safe at home. Barrie Gillings
These are the important players in the creation of the Spirit of Ecstasy mascot, also called ‘The Flying Lady, “Emily”, ‘Nellie’ and other names and which was introduced on 6th Feb 1911.
This is Eleanor Thornton with 1910 Silver Ghost 1404. It was then owned by John, the second Lord Montagu of Beaulieu and, although pre-dating the Spirit of Ecstasy mascot, was the first car to wear one. SG 1404 is now owned by Ian Irwin, who has completed a long-term restoration.
John Scott Montagu was a prominent early motorist and motoring publisher, closely associated with Rolls-Royce Ltd. He opened their new factory in Derby in 1909.
Eleanor Thornton was assistant to Claude Johnson until he joined with Rolls and Royce as managing director. Eleanor was then taken on as private secretary to Lord Montagu
Claude Johnson was a prominent early motorist and secretary to the Automobile Club of Great Britain and Ireland (later the Royal Automobile Club) but joined Rolls in business in 1901. He brought Rolls and Royce together in1904.
Charles Sykes was an artist and sculptor, who painted motoring scenes for John Montagu and R-R Ltd and in 1910 was selected by Johnson to sculpt a mascot suitable for Rolls-Royce motorcars. He made them for R-R from February 6th, 1911 until his daughter took over manufacture in 1928.
Jo(Josephine) Phillips (nee Sykes), an artist in her own right, supervised mascot manufacture from 1928 until end of production in 1939.
John Montagu published motoring books. His book on driving is trite today but, at the time, must have been invaluable for would-be motorists. It carried advertisements for ‘Roads Made Easy’, ‘Alice in Motorland’ and ‘The Motor Pirate’, and these show the close relationships between John Montagu, Claude Johnson and Charles Sykes.
Claude Johnson’s experience as a motorist is clear from this book, much of it gained by his competition driving and job as Secretary to the Automobile Club. Montagu edited the book.
Charles Sykes’ artistic skills were used in Montagu’s publications, and also by Claude Johnson in R-R Ltd advertising, especially their ‘Rolls-Royce Catalogue 1910-1911’ promoting the Silver Ghost. This is now a collectors’ item, with six Charles Sykes’ paintings showing the Silver Ghost in such high society scenes as: Arrival at the Opera... The Country House...The Golf Links...The Meet ...The Covert Side.
Mascots Sculptured by Sykes
The Whisper (or Whisperer) was made by Sykes as a gift for John Montagu. Several copies were made, including a large version. It has been interpreted as a demonstration of the silence of R-R motor cars, or alternatively, as a symbol of the secret romance between Montagu and his secretary, Eleanor Thornton who bore him a daughter.

The Mystery is a real mystery. Although apparently designed as a car mascot, it is far too tall to be practical. Occasional copies appear at auctions and sell for high prices.
The Spirit of Ecstasy is Sykes’ most famous creation. It was entered by R-R Ltd in a competition held in Paris in 1920 to find the World’s best motor car mascot and won first prize and a suitably inscribed gold medal.
“Is my mascot original?
This is the most common question asked by owners. The answer hinges on what one defines as ‘original’. It is obvious that Sykes’ master models are ‘original’. From these he made ‘copies’, usually four. He then used these as ‘masters’ to make agar jelly moulds from which in turn he cast wax patterns to be used to make castings. He then polished these castings and sold them to R-R Ltd to be put on cars. Almost everyone would call these last ‘original’, even though they are copies of copies of Sykes ‘original sculpture’. This is a cabinet in the hallway of Beaulieu Abbey in 1961. Sykes made the middle sculpture as a trophy for the 1903 Gordon Bennett Race. On the left is a Whisper car mascot, now owned by Edward, Lord Montagu. On the right is a large Spirit of Ecstasy. These can be assumed to be ‘original’.
But Edward Montagu made copies of the Whisper in aluminium, mounted on marble, and sold them as “exact facsimiles”. Should we call these ‘originals’ or are they ‘original facsimiles’?

The most iconic of all the Spirits of Ecstasy are the showroom versions, of which there were originally six, 22 inches (560 mm) high, on marble bases, and displayed in RR showrooms in London, Paris, New York, Madrid, Berlin and possibly Buenos Aires. This one, on the right, is shown in the R-R Conduit Street London showrooms and is sure to be ‘original’. So, too, must have been those in the other showrooms. But today, there are copies everywhere, many of them of poor quality, and they are certainly NOT original. Large versions of the Whisper also exist. One was offered by Edward Montagu as a prize in a motoring competition. This is another, in the home of an American enthusiast.
The same enthusiast also purchased a very large Spirit of Ecstasy from a U.S. Rolls-Royce dealership. Should these last two sculptures be called ‘original’? Furthermore, does it matter?
Is it acceptable to put a mascot on your pre 1911 Silver Ghost?
Serious concours entrants go to great lengths to ensure that everything on their car is correct for the car’s age. In Silver Ghost circles, if this applied to mascots, cars earlier than 6th February, 1911 should not wear one, because if they did, judges might deduct points. A telling contrary argument might be that the mascot was optional and an owner should be entitled to have one should he or she so choose and may even have chosen to have one retrospectively.
An even more telling argument is that the 1907 40/50 H.P. car with chassis number 60551 (called by the company “Silver Ghost”, a name eventually applied to ALL pre-1925 40-50 H.P.s) has, on occasion, worn a ‘Spirit of Ecstasy’. The above picture is taken from Jonathon Harley’s ‘Silver Ghost, A Supernatural Car’. The caption reads: ‘The Silver Ghost at Loch Leven making the crossing by ferry to avoid the twenty-mile trip round the head of Loch Leven at Kinlochleven to get to the Hotel Ballachulish’.
Furthermore, the very first Silver Ghosts on test after 6th February, 1911 (1527, 1531 or 1532), were eligible for, but did not have mascots ordered for them but John Montagu’s 1404, on test 5th September, 1910, did have one. Considering the above, fair-minded folk would say that if you want to fit a Spirit of Ecstasy to your car you can, no matter how old it is. A similar argument could be applied to improvements developed by the Company and retro-fitted to earlier cars.
A similar argument could well be applied to mascots other than the Spirit of Ecstasy.
It was offered as a more appropriate hood adornment than the policemen, golliwogs and black cats that so offended Claude Johnson.
Some owners have mascots special to them for religious, social, occupational, patriotic or sentimental reasons. It would be churlish to criticise the wearing of these mascots.
Saint Christopher, who used to be the patron Saint of Travellers. The Old French quotation is: “REGARD St CHRISTOPHE, PUIS VA-T-EN RASSURE’. The translation is ‘Look at St. Christopher, and travel with confidence’.
The Scottish Lion is the emblem to use if you have a Scottish ancestor. This ‘Lion Rampant’ mascot was worn by all Australian vehicles participating in the RREC’s June, 1997 Scottish Tour. They were a great success, especially on the parade down Princess Street in Edinburgh.
The kangaroo mascot is a must for Australia Day and Anzac Day, and works well on overseas trips.
This ‘Be Prepared’ Fleurde-Lis badge adorned the 1929 20 H.P. GVO40, given to Sir Baden Powell by the Boy Scout Movement at a Jamboree in 1929, and which he named ‘Jam Roll’, after ‘Jamboree’ and ‘Rolls’.
Tony Dyas, at the time the treasurer of the UK 20-Ghost Club, commissioned David Gillings to sculpt this mascot of an accountant, complete with quill pen.
Or they may be just very impressive!
This South American Condor was given to a member when he retired as CEO of an South American Company.
An angel reminiscent of the Spirit of Ecstasy. Understandable, as it was purchased at an auction of the contents of the Rolls-Royce Conduit Street, London premises.
A three-dimensional version of the flat St Christopher mascot on the previous page. It is very tall.
This eagle would be a superb mascot for an Alpine Eagle Silver Ghost. Its original owner, Lt. Ronald Fife Angas, bought it in Paris while on leave during WW I.
Or They May Be Just For Fun
This ‘Casper the Silver Ghost’ was a birthday gift to a Silver Ghost owner
This is a model of the 1931 Supermarine seaplane (powered by a supercharged 36 litre V 12 Rolls-Royce R engine), versions of which won the Schneider Trophy three times in succession thus keeping the trophy in perpetuity. The Supermarine later set a world speed record of more than 400 miles per hour.
Mr Toad, the road-raging Toad of Toad Hall, was a sculpture by Jane Gillings for Jeremy Greene. It was so popular that several copies have since been made. This one has been enamelled by the late Glenice Matthews.
The irrepressible Terry Bruce was famous for his Federal Rally shenanigans. This is his “Spinderical Mandragula” the basis of a ten minute spiel which he concluded by declaring that; “I don’t know what it does, but it does it magnificently”. It is, in fact, a device for measuring the efficiency of steam engines.
Post-war cars and their mascots.
Rolls-Royce resumed motor car manufacture shortly after World War II ended but terminated the agreement with Charles Sykes to supply mascots. Thereafter, all mascots were made by the Company. A version of the kneeling mascot was used on the Silver Dawn and Silver Wraith, but the Silver Cloud, Silver Shadow and later mascots were all the standing type and smaller than the smallest of the Sykes mascots. There was some variability in base shape, wing inclination and stance.
“These four examples show the extent to which she could vary from car to car even in the post-war period” from Martin Bennett, Praeclarum June 1999 page 3345
Post-War Cloud and Shadow Mascots
Some countries introduced legislation banning car mascots that might damage pedestrians in a collision. The Company then abandoned the use of a fixed bolt attachment (A) and introduced a spring-loaded mascot (B), which was still firmly attached by bolt or chain to the car but which would deflect in an accident. Around 1972 the Company became RollsRoyce Motors Limited and this was stamped on the rear of the mascot base.
The spring-loaded mascot was superseded by a fully retracting mascot. This was set in the exposed position manually, and retracted when struck lightly. The latest variant can be retracted by the driver at will, or is coupled to the car’s ignition switch.
Notice the difference in the radiator cap profile.
The question: “Is my mascot original?” asks the wrong question. The relevant question should be: “Is the mascot now on my car the one that came with the car when it was new?” You cannot rely on what previous owners tell you and, as you will see later, the chances are about 50/50 that the first owner did not even order a mascot. To find out whether your car’s original purchaser did so, you must consult the car’s R-R Conduit Street Sales Card.
The Spirit of Ecstasy Mascot was an Optional Extra from 1911 to 1939
Consulting the Conduit Street sales card records of the 20,000 or so cars manufactured between 1911 and 1939 to determine whether a mascot was ordered is a daunting task.
The results:
Silver Ghost: 1911 - 1914 only 10% had mascots; half of them retro-fitted 1914 - 1919 only 74 mascots ordered; about 10% of the total sales 1919 – 1920 about 25% ordered with mascot 1920 - 1925 the 25% continued to the last of British Ghosts New Phantom about 50% ordered with mascot Phantom II also about 50% Phantom III nearly 100% ordered with a mascot 20H.P. 1922–23 25% ordered with a mascot 20H.P. by 1924 & 20/25H.P. about 50% 25/30/Wraith a great increase to about 95% The Spirit of Ecstasy Mascot was an Optional Extra from 1911 to 1939 The Parts Books for the Silver Ghost (Series J-P) and the New Phantom (1926) list the mascot part number and code name as E 18328a, Cellulose. Consulting the Conduit Street sales card records of the 20,000 or so cars manufactured between 1911 and 1939 to determine whether a mascot was ordered is a daunting task. The results: These identifiers changed for other models. For the 1928 20H.P. they were E52356, Meole. This confirms that these two mascots differed and so did later mascots. The parts books also state that the Mascot was “only supplied when specially ordered”. Jo Phillips (nee Sykes) has written that her mascot production was about seven per week from 1928 to 1939. This suggests that only about 40% of the Rolls-Royce cars manufactured between 1911 and 1939 were ordered with mascots. We know that the Sykes’ ceased mascot manufacture after 1939 but most pre-WWII Rolls-Royce cars seen today wear mascots. It must therefore be concluded that many, perhaps half, of the mascots now on these cars are copies of Sykes mascots and were not made by him or his daughter. Such mascots, if made by a competent operator, would be difficult to detect. Only about 40% of the 20,000 cars delivered between 1911-39 were ordered with mascots.
TOWN OR PARKING CAPS
Unlike the mascot, all pre-1939 Rolls-Royce cars were sold with a radiator cap. Prior to 1911 the cap had a small hexagon top, with the code name ‘Knead’ and part number S430. After that date the Silver Ghost parts book listed the mascot as E 18328a, with the name ‘Cellulose’ and its matching cap E 18326, named ‘Cellarman’. (There was, in true Rolls-Royce fashion, no E18328). The numbers and names for mascots and caps of later models can be found in the relevant parts books. The early Knead cap became known as the ‘Town’ or ‘Parking’ cap when mascots became available, because the mascot, plus its cap, was often removed to prevent theft.
The original early caps were cupro-nickel. Some were probably German silver. These are a good match for the German silver radiators. Caps not made by R-R are usually brass or bronze and nickel or chrome-plated to match the radiator. These can be identified by a rare earth magnet, which is attracted by the plating but not by cupro-nickel or German silver.
The town and mascot caps have a different hexagon. The town cap hexagon is around 0.375 inches high and 1.0 inch across the flats. The mascot cap hexagon is 0.15 - 0.25 inches high and 1.3 - 1.5 inches across the flats.
Some New Phantom and Phantom II mascot caps have octagons in place of hexagons. The across the flats measurements are nearly the same, 1.4 - 1.5 inches, with the same height. The octagon was probably introduced as it makes a better match to the abutting round base of the larger mascots.
Phantom II compared with a Phantom III
There is a regular progression of diameters of radiator filler spouts. The outside dimensions are 2.0, 2.25, 2.5 and 2.75 inches. 2.0 for Silver Ghost, 20 H.P. and New Phantom. 2.25 for late new Phantom, Phantom II and 20/25. 2.5 for late Phantom II, 25/30/Wraith. 2.75 for Phantom III. All, however, have the same thread size of 16 BSW threads per inch. The size changes may not be exclusive to a particular model. So to avoid misfits, measure the diameter of your radiator filler pipe before you order a cap.
The very earliest type which was only supplied for 1911-14 cars.
The hollow base fits over a modified town cap
The very first mascots were made with a hollow base, which was fitted over a cut-down parking or town cap. This system not only made mascot manufacture difficult, it also required the use of a pipe wrench if the cap was too tight to undo by hand. Thus all except the very early mascots have a flat base abutting a wide hexagon or octagon, on which a suitable open-end spanner can be used.
Some variations of radiator adornments
Rolls-Royce radiators have been adorned by a variety of mascots and devices. A well-known one which excites much comment is the extension used by the R-R team cars in the 1913 Austrian Alpine Trials. Because the bonnets and radiator caps had to be sealed, no oil or water could be added during the trial stages. Rolls-Royce found that in steep descents with a fast-revving engine, water could be lost via the overflow pipes within the radiator. To avoid this, extension pipes were fitted to the overflow pipes to raise the level at which overflow could occur. This required a watertight extension to the usual filler pipe, with the usual filler cap on top. This is one such on an actual Austrian Alpine Trials Silver Ghost. A bracket for attaching the seals can be seen.
Although the R-R Company car AX201 (Chassis No 60551) is shown earlier wearing a Spirit of Ecstasy mascot, it usually wears a Royal Automobile Club badge. Many owners of pre1911 cars follow this tradition
Some practices are best not followed. This is a mascot seen on a Springfield Phantom I, “The Dreamboat” which was denied entrance to an RROC Inc Rally in the late 1950s. The propeller, bug shield and electric light were deemed by the Clerk of the Course to be inappropriate enhancements.
The “Anti-Splash” Device"
In the early 1930s, Rolls-Royce introduced the anti-splash device, so-called in the parts books, but usually called, incorrectly, the steam valve. It is used on post-1930 cars which have an external ‘dummy’ radiator. The radiator cap seals the outside ‘filler’, and a brass plate seals the top of the ‘filler’ of the actual radiator underneath. There is no way that a lightly spring-loaded brass plate abutting the face of the actual radiator top will retain steam. All it does is stop water splashing out of the radiator and reaching the overflow pipes outside. But to do this it has twelve components. Why so complicated? The same effect can be achieved with six.
It is a mystery why the company introduced this device. From 1904 to 1930, R-R radiator water was free to flow down the overflow pipes, and no attempt was made to stop ‘splash’. After WWII, cooling systems were designed to run ‘under pressure’, and then the radiator cap actually ‘sealed’ the radiator, with an inside pressure of a pound or two.
A complicated mechanism with 12 pieces.
A simpler solution which still does the job.
Identifying Pre-war Mascots by Names, Dates, Signatures, Bases & Wings
Numbers on the illustrations refer to those identifying the pictures on pages 5030-5033 of Praeclarum, (See rroc.org.au) or 8501-8504 of The Flying Lady. 20 If your mascot does not seem to conform to the above information, please remember the mantra re all things Rolls-Royce: “Never say Never, and Never say Always”.
Mascots made by Charles Sykes or Jo Phillips are always identified by a date (Feb. 6th,1911 or 6.2.11 or 26.1.34) and a signature (Charles Sykes, or C Sykes). These identifiers will also appear on post-1939 copies of genuine Sykes mascots. There is no particular sequence to the form of date or signature but the full Sykes signature will use the Greektype ‘e’ and ‘s’. Some post-1930 mascots will have a C. Sykes signature in normal upper and lower case lettering and are certainly not an actual Sykes’ signature, for the probable reason that he did not sign them, as his daughter Jo Phillips had taken over their manufacture.
KNEELING MASCOTS PII, 25/30,Wraith, PIII
The kneeling mascot was introduced on January 26 1934 (Australia Day), probably because owners of sleek , sporty R-Rs wanted a lower profile mascot. The date is scribed on the right hand side of the mascot, and is signed ‘C Sykes on the left hand side, with the period being between the arms of the C, and not on the base line.
The Sykes mascot should not be confused with the post-WWII kneeling mascot used by the Company on the Silver Dawn and Silver Wraith. The latter has less artistic and more mechanical in detail and the wings are much wider. Also, because it was not made by Sykes, it has no signature, and thus no 26.1.34 date.
All English Mascots Before 1939 (except early SG)
With one exception, all English R-R mascots had, inscribed under the right wing: TRADE MARK REG. and under the left wing: REG. U.S. PAT. OFF. The exception was the very first mascot which has no ‘under-wing’ inscriptions. The size and orientation of the under-wing lettering varied considerably with different mascots and was hand-scribed. For post WWII mascots, the under wing lettering was stamped. Some owners may find, under the left wing of their mascot, an additional inscription, the letter ‘R’ followed by a date, eg: ’99. This indicates that it was made by Barrie Gillings in 1999 and identifies it, unequivocally, as a 1999 ‘Replica’ of a Sykes mascot.
Springfield: 1921 -1926
The mascots fitted to the U.S.- manufactured Springfield cars were made by the Gorham Silver Company of Providence, Rhode Island, USA. There are two types, the earlier and rarer one, (A), has ‘ROLLS-ROYCE’ scribed on the right-hand horizontal surface of the plinth or stamped on the front of the vertical surface. The later one, (B), has a sharp edge on the plinth and ‘ROLLS-ROYCE’ on the right and, on the left, (C) ‘REG. U.S. PAT. OFF.’ in the spidery type font used by Springfield.
We repeat: never say “never” and never say “always”.
FINGERS AND TOES
Over the years, some, and sometimes most, of the fine detail of a mascot may have been lost through over-zealous polishing prior to re-plating. The first to go is usually the detail of the fingers, because their direct exposure to the polishing mop, as here, with only two fingers visible.
Toes suffer a similar fate. Early mascots had anatomically correct toes. Later ones had simple grooves suggesting toes and even these could be obliterated by over-polishing.
Very few electroplaters have any concept of the careful polishing needed to preserve detail. In this poor quality replica the detail in the wings and body has been polished off, leaving a smooth surface.
This 1958 photograph is of a mascot owned by Stanley Sears. It was then about 30 years old. Imagine what it could look like after an additional 50 years or so of polishing.
VARIATIONS
Several authorities insist that the 20 H.P. mascots were of two types, with either the cylindrical ‘small cheese’ or ‘large cheese’ base (both below to the same scale).
Each has ‘Rolls-Royce Ltd Feb.6th 1911’ on the base. The small cheese is signed C Sykes, with o fullstop and the large, Charles Sykes. Later 20 H.P. mascots have rounded bases, and may be signed R-R Ltd 6.2.11 and C Sykes. So: “Never say Never, and Never say Always”
Some Suspect examples:
This mascot is not signed or dated and is almost certainly NOT a Sykes mascot, even though it might look very clean and detailed as this one does. It also has a base which is clearly modelled on an early mascot.
This mascot is very detailed and is similar to a genuine New Phantom Sykes mascot. But it has no signature or date. It looks fine, but is not a Sykes mascot.
This mascot is almost certainly a copy of the previous mascot and has excellent detail but is a zinc injection moulding, with the parting lines of the five-part mould clearly visible. It was purchased at a market stall in Malaysia for $5. At this price, it can be left on the car without worrying about theft.
What Are Caps & Mascots Made of ?
Authorities have various opinions about the metals used in Sykes mascots. It is clear that many of the early ones were cast in German silver or alloys of a similar appearance, and were silver-plated. The silver-plating has by now been almost completely removed by assiduous polishing. For a probable explanation of the alloys used, I rely on Jo Phillips who took over mascot manufacture from 1928 to 1939.

The silver-plating has by now been almost completely removed by assiduous polishing. For a probable explanation of the alloys used, I rely on Jo Phillips who took over mascot manufacture from 1928 to 1939. Jo sent me these notes for her lecture on the mascot to the Rolls-Royce Enthusiasts’ Club. Copies of the notes have been sent to the Sir Henry Royce Foundations in the UK and Australia for their archives. A CD of her lecture is available from RREC’s Hunt House in the UK
Alloys
Various alloys have been used to make mascots and caps. Mascots are always castings, but caps can also be machined from solid bar. Early radiator caps were cupro-nickel (90% copper, 10% nickel). The alloy formulations specified by Jo Phillips in her lecture notes should be considered approximate. The German silver, white metal and bronze alloys used in foundries have a bewildering variety of formulations.
Bronze is an alloy of: copper 90% - 60% and tin 33% - 10%, perhaps with other additions. German silver is an alloy of: copper 60% -45%, zinc 32% - 50% and nickel 22% - 6% but no silver. White metal is an alloy of: tin 89% -80%, lead and/or copper 6% - 1% and antimony 20% -12%. Brass is an alloy of: copper 90% - 60%, zinc 40% - 10% and other:- aluminium, manganese, phosphorus etc. 10% - 1%.
The book Brassfounders’ Alloys (E&FN Spon Ltd, Haymarket, London, 1918), lists 199 different casting alloy formulations and your mascot could be made of any one of them! If your mascot has lost plating anywhere and the underlying metal matches your pre-1930 radiator, it is probably German silver or a white metal or white bronze formulation but this is not an infallible indicator of a genuine Sykes mascot. R-R Ltd probably fitted the bolts to the mascots and made all the radiator caps. Sterling silver mascots or gold mascots have been supplied on request. The latter is usually plated.
HOW ARE THE MASCOTS MADE?
The Sykes made mascots using the ancient ‘lost wax’ process. A wax pattern is encased in heat-resisting mould material and heated to melt out the wax. Molten metal is then poured in and when cool, the mould is chipped away from the ‘casting’, which is then smoothed and polished.
The steps are:
