Dieterle's Red 7 from Sep 13, 1944

[rbakerj]

How do I get info, like the Werk Nu and where and when a particular Bf-109 was produced? Any production details are welcome, like subcontractors producing components, even a factory photo of the this airframe on the assembly line, if such a picture would exist. I am writing a story as some of you know about the loss of a B-17 on the Sep 13, 1944 mission to Merseburg. Mag the Hag II, a B-17 with the 92nd BG, was herrausschuss from its formation by Lt. Manfred Dieterle of 2./JG 300. He was flying Red 7 that day. I found a pic a Mag the Hag II getting the large white triangle and black B painted on her vertical tail surface, a rare pic to be sure.

Thanks,
