No, she was definitely a C.202 and 95% of the C.202 had the wing 7,7mm removed.
Moreover no C.205V fought so early in the desert air-war and the first Series of the C.205V had only 2x12,7mm and 2x7mm.
I think that playability requires some "tuning" of gun lethality. However, I do believe that 12,7mm BREDA-Safat mounted on Macchis are a lil' weak.
