the Ta is Walter Loos green 4 of Stab./JG 301 found now at the smithsonian and it will go under a major refit and painting back into a close original colouration. I do beleive Walter passed away this past year as he would of grinned from ear to ear to seen his old mount back into condition.
the pilot sitting on the wing of the Fw 190A-8 is freind and RK ace Willi Unger. It is a propaganda shot of 12thSturmFw's/JG 3 with the stupid Kregs-gerat or reverse firing mortar used by the staffel operationally for about 20 days. The thing was a waste of time although attacking the bombers from the rear in the SturmFw and then coming out the front to be fired on by a rearward facing rocket would be disheartening to bomber crews I can imagine. This is Yellow 17 which Willi never even flew as it is not logged at all in his flugbuch. There are about 4 pics taken of him and this goofy a/c.
