Hi,
many thanks Christian for the identification of the Zwinger !
A nice website by someone i was in contact with in the past :
http://www.anciens-aerodromes.com/?p=2097
Infact M. Galland was of course in the Audembert airfield, as he was the Kommodore of the JG 26.
Maybe the picture was taken after a victory by M. Galland ?
His Me-109 don't have the unit mark on the side.
Sincerely Yours,
Vincent
