Vintage Armstrong Siddeley Cheetah Aviation Ashtray - Mappin & Webb Princes Plate - Mid 20th Century A fine vintage aviation ashtray directly connected to the golden age of British aeronautics. At its center is an engraved representation of the Armstrong Siddeley Cheetah radial engine, one of the most widely used British aircraft engines from the 1930s to the 1950s. This engine powered several now-iconic aircraft of the period, including: Avro Anson – RAF training and coastal reconnaissance aircraft during the Second World War Airspeed Oxford – the principal advanced trainer used for British aircrew instruction de Havilland DH.89 Dragon Rapide – famous civilian and military transport aircraft Percival Proctor – communication and radio-training aircraft Founded in 1919, Armstrong Siddeley occupied a distinctive place in British industrial history, producing both aircraft engines and high-end motor cars in the same world of engineering prestige as Rolls-Royce. Its aviation-engine activity later became part of Bristol Siddeley in 1959, before that company was acquired by Rolls-Royce in 1966. The Armstrong Siddeley name therefore belongs today to the wider technical and industrial heritage of Rolls-Royce. This ashtray was made by Mappin & Webb, bearing the Princes Plate mark and the prestigious London & Sheffield manufacture reference, adding an additional layer of British decorative and industrial pedigree.
