Photographed at Messerschmitt "Oberbayerische Forschungsanstalt" clandestine development department at Oberammergau. Taken in April 1945 when late snowfalls occurred. Just watch the Bad Wörishofen photographs.
Very interesting photograph - prototype seems to be undamaged and only shoved outside the hangar to crete space for whatsoever.
