On the left Chaplain Captain Wilhelm Stempor, on the right Captain Janusz Franckiewicz, the person in the cabin unidentified. The plane Mustang IV with Division’s 303 emblem, year 1945, not much to do, boring.

‘Polish’ Caudron in Villacoublay (France) with cut out Polish chess-board. My source suggests that it was taken by Germans as a trophy, but may be it was just vandalised. The plane was used by Sub-Lieutenant Żukowski.
