It's really up to Ghost. I hope he knows that you don't have to know who the pilot was to submit a skin. I must say though, I am interested in the reason behind the green markings, more so than who the pilot was.
I really don't care about the skin aspect at all. Just the History.
Between you and me... I submit that those are JG54 Stab training rides (that were once kombat used) utilizing green in winter over usual white to differentiate from Kombat Stab (White/Black) and this is because 3 Div.Flieger-SchulDivision was based at Siverskaya temporarily in the Winter of 41/42.
I can not prove this beyond any doubt with my current inventory/sources...but I will continue if you wish me too. I am certain that photo was included in the book as just an example of 54th winter rides...hence Trautloft makes no mention of it being his plane, nor does the caption or text.
Someone (prob. a profiler) assumed such...that is all.
