Flyingmule's camo is almost laughable.
That being so, somebody was attempting a similar scheme, but with realistic whitewash patterns.
[EDIT: I wonder how they're doing on that... haven't seen any progress in a while...]
As for the yellow leading edges, I'd be skepticle to the point of disbelief until you find real evidence to prove it existed.
Seems the majority of IL2 skin downloads are fabricated, out-and-out made up, or just plain inaccurate. Some are historical, but others are just fantasy. They don't have the same rules AH has, and as such you really can't trust them as "historical".
