A bit more on Karl Hagemann..
Shot down in "Black 13" with wounds on 19 December, 1944 by Wispenthal. Despite his wounds, he managed to bail safely. His two known victories, both P-47's on 19 December, 1944, no location given....
Edit: Any idea what the Fw 190 of LT Rudolf "Rudi" Rademacher of 1/Erg/JG-1 (8/44) aka JGr-Nord, might have looked like as in camouflage? His was a, as you can see, a Fw 190A-8 Werk# 350193 and "White 13".
