Hello,
Thank you Mr. Morrison.
We can see three pictures of that plane here:

What about the "Winkel Doppelbalken" we can find on same page?? Prien is giving it as JG 77....
It happens that Stab II./JG 77, as indicated by Prien for that last plane, was in the balkan too (Deta, Vrba ... and it's close enough from Bitolj) in March-April 1941 period.
It happens, too, that the small vertical bar - say "B" - we can see on the 6453 looks too thick to be a letter but match pretty much to be a Balken or to be a Doppelbalken.
So sincerely I wonder if
1/ Is Prien caption right?
2/ Is 6453 caption right?
Cheers, Franck.
