This line up of 19 Squadron Supermarine Spitfire Mk Is was taken at RAF Duxford in May 1939. The squadron became the first to receive Spitfires, in August 1938, and its Mk Is remained in service until replaced by Mk IIAs in September 1940.

K9912 was one of the later production Spitfire Is, upon which the curved hood was standardised, and the de Havilland three-bladed variable-pitch metal propeller was introduced. This particular Spitfire served with 65 Sqn until it was struck off RAF charge in May 1940.
Spitfire I K9787, the first of a production batch of 213 aircraft delivered to the RAF between July 1938 and April 1939, went to the A&AEE and RAE before joining the PRU.
