The first Spitfire into service was delivered to No. 19 Squadron at Duxford on 4 August 1938. The use of 100 octane fuel was approved for Spitfire Squadrons by 24 September 1938.32 Fighter Command noted on 6 December 1938 that Duxford, Debden, Northholt and Digby had received 100 octane fuel.32b As of December 1938 Nos. 19 and 66 were based at Duxford and were the only RAF units then equipped with Spitfires. The Air Ministry noted in a memo dated 12 December 1939 that "100 octane fuel is approved for use in Hurricane, Spitfire and Defiant aircraft, and state that issue will be made as soon as the fuel is available in bulk at the distribution depots serving the Fighter Stations concerned." 32c
