Just found interesting webpage with letters and photos of Leopold Wenger, among them following photographs of Fw 190 G-3s of 4./S.G. 10 in the East. Have not seen any photos of Fw 190 Gs from Eastern front previously... are you aware of any other of this kind (from ebay etc.)?
best regards,
Pawel
ps. Also... the 'white 5' seems to have only its left aux. tank attached, would it be possible to fly the a/c in this condition?
