Wow, thanks for the information, Doug and Matti!
I don't know who the Staffelkapitän was following Zuzic's death on 19 August 1943, but Faber apparently became Staka on 8 October 1943. Maybe 8./JG 1 did not have a Staffelkapitän in the meantime? Or Heinrich Overhagen was the Staka in that period, though he (also) replaced Faber after 3 November 1943...
Ries flew black 3, most likely this aircraft (a Regensburg Me-109, Werk Nr. 160349)?:
Attachment 6050
And several pictures of Husser are to be found on the web, though it's hard to tell when he flew in the units Tom Kracker mentioned. He did flew in III./JG 1, but when exactly remains hard to say.
But you really helped me out, thanks again!
