I "think" i seen a hungarian 210 with double 40s in the wingroots in a book years ago, so not sure about the fuselage vs wingroot dilemma. Gonna find that book again and get the scaner working.
Krusty is right, found a source what clearly says it was one center mounted 40mm
i believe fuselage mounts, right under the nose.
That's a BK5 muzzle in the pic. The Hungarian 210s used the smaller flak guns.
Thought I read somewhere that a certain varient 410 had a 50mm with 21 rounds.
It wasn't German. It was a 40mm ground mounted AA gun I think, adapted to fit.
I dont think so. M36 codenamed hungarian cannon, a license production but idk if that was the flak41.
