Found this page with lots of research on Soviet cammo and some profiles.

P-39s
Yak9Ts
etc.
Looks like the web sight is by the authors of
Soviet Air Force Fighter Colours 1941-45 Skins for Soviet A/C are a bit lacking. Yak skins also are kind of iffy from the research I've done. Especially the 9U.
And, I figure the Yaks are probably in the cue for a remodel so Greebo could use another bit of research material.
