ARMSTRONG SIDDELEY MOTORS 1919 - 1999:
Part 1 - The Early Years

BEGINNINGS
Armstrong Siddeley Motors Ltd. was officially formed on 1st November 1919 although agreement to create the Company dated from 19th February of that year. The Company was born out of the act of the Siddeley Deasy Company being taken over by the Armstrong Whitworth Development Company. There had, however, been Siddeley cars before 1919.

John Davenport Siddeley set up the Siddeley Autocar Company in 1902 and in 1903 four Siddeley models were shown at Crystal Palace and by 1905 there was a choice of more than a dozen models from two-seater to landaulet. Some of these early cars have survived, one being in the possession of the late Peter Baxendale's family and one being on show at the Rolls Royce Heritage Trust Museum in Mickleover, Derbyshire.

In 1905 John Siddeley joined Wolseley as Sales Manager and from then until 1909 a series of Wolseley-Siddeley automobiles was produced. These were most impressive cars. One of the cars is believed to have belonged to Queen Alexandra, patroness of the Company, and John Siddeley is believed to have driven King Edward VII in front of Buckingham palace in one in 1906. A five litre 1909 model is believed to be still in existence in private ownership and a preserved Wolesley-Siddeley Phaeton resides in a museum in Bergeyk in Holland.

In 1909 John Siddeley again moved on and joined the Deasy Motor Company, becoming Managing Director in 1910. The Deasy Motor Company was established in 1906 at Parkside in Coventry by Henry Deasy and its early business was importing cars from France and transforming them for use in this Country. Under Siddeley's management the Company was substantially expanded, growing from 200 employees in 1909 to 5000 in 1919.

Siddeley started to obtain chassis from Rover, engines from Aster and Daimler and bodies from various contracted suppliers. In 1911 the Company was using the Daimler Knight engine, a unit of particular quietness. Not content with the engines as supplied Siddeley had them stripped, polished and tuned resulting in an even quieter unit described by one impressed journalist as "As silent and inscrutable as the Sphinx".

THE GREAT WAR
In 1912 the name of Siddeley-Deasy was in use and by 1914 The Company had become a successful car builder. The Great War changed things dramatically. The size of the workforce increased tenfold and the products changed also. Lorries, ambulances and staff cars rolled out of the factory gates and, from 1915, airframes and aero engines too.

ARMSTRONG SIDDELEY MOTORS IS BORN
With the return of peacetime things again changed and Siddeley Deasy merged with Sir W. G. Armstrong's Armstrong Whitworth Development Co. and a subsidiary, Armstrong Siddeley Motors Ltd. was created. This was the company that produced Armstrong Siddeley cars thereafter until manufacture stopped in 1960.

The first cars made by the new company were 30hp models, a 4960cc six, and the first style of A/S V fronts were incorporated in the design. (see the reproduction of the announcements and illustration of November 1919 published in the November 1999 Sphinx).

The 30hp was a substantial vehicle in all respects, being sold to the aristocracy including the then Duke of York, later King George VI, and to the carriage trade.

The 30hps were followed by an 18hp model introduced in 1921 having a 2318cc engine and by a 14hp four cylinder model in 1923. Unlike the 30s and the 18s, the 14hp sported a flat radiator. The 14 became a very popular model and over 14,000 were built in the next six years, many going for export.

Changes to the models took place in 1925 when Mk II models were introduced on the 14, 18 and 30hp chassis.

The two smaller cars had revised chassis and the 30 received a new mono-block engine instead of its original bi-block engine, the origins of which could be traced back to 1914. In 1927 a 15hp six joined the range.

TECHNICAL INNOVATIONS
1928 saw the introduction of the Wilson Epicyclical fluid flywheel drive and, what W. G. McMinnies (Publicist to A/S) called the self-changing gear, setting the style of Armstrong Siddeley cars which was to continue almost unchanged, apart from the introduction of the Newton clutch in 1936, until automatic gearboxes were offered on the 346 Sapphire some twenty five years later. The archetypal Armstrong Siddeley car had arrived.

Through the thirties the V radiator style was followed exclusively, the flat radiator of 14s etc. disappearing from production, identifying an array of models as unmistakably A/S. Between 1929 and 1939 there were at various times 12s, 12+s, 14s, 15s, 16s, 17s, 20s, 20/25s, 30s and the doyen of them all, the 4960cc Siddeley Special.

MORE THAN SIMPLY CARS
It is important to recall that Armstrong Siddeley was not just a car company.
Throughout the inter-war years it built aero engines and aeroplanes. It also became involved in the construction and powering of railcars (See April and July 1997 Sphinx). Subsidiary and associated companies (Armstrong Whitworth Aircraft, Improved Gears Ltd., the Coventry Pneumatic Railcar Co. etc.) came along.

John Davenport Siddeley remained at the helm of The Company until 1935 when A W Aircraft was sold and became part of Hawker Siddeley Aircraft, the Hawker part of the company being based in Surrey and having its origins with both Messrs. Sopwith and Hawker, and in 1936 Tommy Sopwith became Chairman of ASM.
