A razor sharp photograph of an early, Armstrong Siddeley Jaguar-powered D.XVI fighter. The markings are apparently Italian - it seems that 157 is an Italian MM serial number. The aircraft was not accepted by the Regia Aeronautica folllowing test flights. It arrived in Mukden (Shenyang) on 25 July 1931, shortly before the Mukden Incident. It was reportedly tested in Peking in August 1931. Photo from: ETH-Bibliothek Zürich
