I'm at a loss as to how this was mistaken for an A6M in the first place. >.O
Probably due to the A6M Zeros facing against the F6F Hellcat in most aerial battles?
In addition, I am unable to identify the variant of the Ki-61 [the -I variants used the Ha-40, the Japanese version of the DB 601 engine while the -II variants used the Ha-140, the Japanese equivalent of the DB 605 engine. Also, without the front view of the wings, it is not known whether the Mauser MG 151/20 cannons or the Ho-103 machine guns are mounted inside (or even none at all as evidenced by the 244th Sentai)].
