MM.91150 was a Fiat G.55 that on 4 August 1944 was used by test pilot Serafino Agostini to pick up Allied OSS agent Lt. Francesco Gentil, transferring him over the front-line to the Allied-held Piombino Air Field. Thereafter the RAF took possession of the aircraft, giving it the code VF204 and transferring it to the Central Fighter Establishment of Tangmere, Great Britain, where it was tested till lack of spares grounded the aircraft. On 17 March 1945, with the identification number VF204 still applied, it was put in depot at RAF Ford. It subsequently may have been scrapped there somewhere between 1946 and the early 1950ies.
