Yeah unfortunately following the default 109K skin from IL2 has led you astray.
This scheme was last used on 109G-6s, Im not sure which factory used it but I pretty sure it was canned When the G-10 game along, I've seen plenty of G14AS's with the even early type of wing camo (109Es in the BoB type) but again not this type, Japos 109K markings and Camouflage has good refs to wing patterns used on all blocks of K-4s
