If we have the Bf109E, Spitfire I, Hurricane I, A6M2, P40B/P40E, C202, etc....
then the D520 may as well be fielded. I have yet to dig too deep into the research, but I have a gut feeling more D520's were flown than the C202. As much as many of us roll our eyes when "France" is menitoned, still the D520 can run with any plane in the early war arena.
