Armstrong-Siddeley
United Kingdom: 1919 - 1960
The Armstrong-Siddeley company was formed in 1919 through a merger of the military-industrial company Armstrong Whitworth Development Company with the car manufacturer Siddeley-Deasy.

Its main products were prestigious cars, and in the military field, it left a memory with a creation of small series and prototypes rather unusual cars, as well as it was involved in the production of aircraft engines. Armstrong-Siddeley has made its last car in 1960, and the business of manufacturing aircraft engines has been merged with Bristol Aero Engines.
