Pardon my ignorance Nigel, were the D520's originally made by the french or italians?
French. It was France's intended main fighter type at the Armistice, and production continued off and on. It never finally entirely supplanted the other types; Curtiss Hawk-75s were still very much in evidence during Operation Torch, for example - but by the end of the Vichy period it was their principal fighter.
When the Vichy air force units in Metropolitan France were disbanded following the German/Italian invasion of the Unoccupied Zone in November 1942, the aircraft were confiscated and shared between the victors. A number went to the RA, as here, while others were kept as advanced trainers by the Luftwaffe, or sent on to client states such as Bulgaria or Croatia.
Their final operational use was at the hands of FFI - French Interior Resistance - air units, which were thrown together at the liberation out of ex-French Air Force personnel and any aircraft they could get their hands on - mainly D.520s and Ju88As.
