Thanks for the reply Rune.
The photos were taken in Heeresgruppe Mitte during Barbarossa. My grandfather's line of march with the Luftwaffe took him to the following places, so it seems likely the Il-4 was found at an airport/aerodrome along this route:
29-06-41:- Slusk
06-07-41:- Bobruisk on the Beresina
09-07-41 to 09-08-41:- Stary Bichow on the Dnepr
12-08-41 to end Aug.41:- Ponjatowka near Roslawl
02-09-41 to 03-10-41:- Schatalowka + Seshchinskaya
09-10-41:- Paumowa
15-10-41 to 20-10-41:- Juchnow
26-10-41 to 13-11-41:- Malojaroslawez on the Protwa
The photos were developed recently from a reel of negatives I found concealed in an old safe back home in Germany. I've put several up on the web at
