The Coventry collection constitutes the finest record of Armstrong Siddeley achievement anywhere, encompassing motor cars, aero engines, rocket engines and engines for industrial and marine applications. The collection is housed alongside the Derby Branch collection in Derby.
Among the exhibits are several rare and unique examples of Armstrong Siddeley, Bristol Siddely and Rolls-Royce products including:
There is also a small workshop at the Ansty site, near Coventry. Current restoration projects include Viper Turbojets, rocket engines, a Cheetah radial and a 1937 12+hp Armstrong Siddeley car.
