Hello 'Foute Man' and Peter,
I just checked out your new book Peter, on the BoF, and got a bit confused as the back side writing of the photo, translated into English, reads:
“During the last mission over France our Kommandeur, Oberst, Kammhuber, was shot down, we found his aircraft dismantled at a shelter by an airport. 1940”
.....and your description clearly indicates a Ju 88 when describing how the aircraft was downed as the He 111 did not have any dive brakes.
The writing on the photo can of course be wrong regarding which aircraft he was in when downed.
Regarding the emblem:
This is the emblem of Stab/KG 51 as it is published in "Luftwaffe Embleme 1939-1945", Ketley and Rolfe, Bernard & Graefe Verlag.
This can give the indication that the upper right emblem had a red background colour.
The large shield on which the three emblems are located on the He 111 is more difficult. A darker shade of Blue??? Only a guess from my side.
Regards
Goran
