Well, I did a quick search - there are several historical skins for each late mark (G-6 through to K-4) at Mission4Today, for Eastern Front based JGs - JG52, JG5, and various other Groupe from other JGs that served in the East. I can also make a skin, if you need it, though I a bit busy right now, so I can't promise a large pack (you can check my work here at AAA in the skins section). AviaSkins also have lots of stuff, though most of it is posted on their forums - certainly everything you'll need for the VVS RKKA. :wink:

Otherwise, as Phas3e said, you'd need a good "blank" skin for each type, but there are plenty of those.
