This is Tamiya's 72nd scale kit, with prop and wheels replaced from an Airfix boxing of the early Spitfire. Exhausts are a resin product form SBS Model.
Spitfire L1090 was part of the first batch ordered in 1936 (serial range K9787-L1096), and by the spring of 1940, had found its way to Canada. At an RCAF testing center, performance was tested against the P-40, and it was concluded that the Spitfire came out on top.
Also, L1090 was involved with testing a newly designed anti-gravity suit by a Toronto doctor, Wilbur R. Franks. It is believed fives times as many allied airmen survived the war due to this invention, and would go on to be the forerunner of G-suits for future air force pilots as well as astronauts across the globe.
