Welcome to the Armstrong Siddeley Owners Club

Car Of The Month

1931 Mk2 12hp 2-seat Tourer

12hp conv

In October 1930, Armstrong Siddeley introduced the Mk2 12hp model and increased its 6 cylinder engine size from 1236cc to 1434cc. This did not effect its RAC rating of 11.9hp. The cars were available in two types; one was "The New 12hp" with four speed pre-select gearbox and a V-radiator shell and the other was "The Economy model" with three speed pre-select gearbox and a flat radiator shell. Around this period, several body styles were available from the factory for 12hp cars together with others from outside Coachbuilders including Salmons, Maltby, Charlsworth and Maddox. Some 7750 Mk2 12hp cars were built between 1930 and 1935.

This particular car was first registered in Jan 1931 and its first owner was Frederick Prance of Basingstoke. He was a solicitor and ex-Mayor of Basingstoke. When he died the car passed to his wife who used the car after the war and eventually sold it in 1957. Interestingly a current club member who lived near to Mrs Prance as a boy remembers the car being driven around the village in the 1940s. The current owner purchased the car in 2014 and, despite some work having been done, after a detailed inspection he realised that it needed a full "back to basics" restoration. He rebuilt the engine, made a new water pump and reconstructed virtually all the ash frame and floors. He made new wiring looms and a walnut veneered dashboard. In fact every part of the car has been meticulously restored to make it the super example it is today and which is used regularly around his home in West Wales.
