Armstrong Siddeley

Armstrong Siddeley was a British engineering group that operated during the
first half of the 20th century. It was formed in 1919 and is best known for the
production of luxury vehicles and aircraft engines.

The company was
created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a
manufacturer of fine motor cars that were marketed to the top echelon of
society. After the merge of companies, this focus on quality continued
throughout in the production of cars, aircraft engines, gearboxes for tanks and
buses, rocket and torpedo motors, and the development of railcars. Company
mergers and takeovers with Hawker Aviation and Bristol Aero Engines saw the
continuation of the car production which ceased in August 1960.

The
company was absorbed into the Rolls-Royce conglomerate which was interested in
the aircraft and aircraft engine business. Eventually, the remaining spares and
all motor car interests were sold to the Armstrong Siddeley Owners Club Ltd,
which now owns the patents, designs, copyrights and trademarks, including the
name Armstrong Siddeley.
