Guys
What speaks against any JG unit is the time and place. I doubt very much that ANY Jagdgeschwader operated any Emils in February 1943. At this time even the F model was on its way out.....
At the time Stab./SchG 1 was based at Voroshilovgrad and still used the E-model. The statement nearby Stalingrad is fuzzy and can be "anywhere" depending on the indivuals meaning of "nearby". You just need to travel to the north of Sweden to know what I mean....
But I agree with all others that the photo is very good indeed.
Cheers
Stig
