I am trying to find out to which Luftflotten Stab JG 54 was attached from May 1942 to December 1943.
First of all does anyone have any information on airfields used by this unit and the rough dates?
If not can any-one tell me in which Luftflotte areas Oberstleutnant Johannes Trautloft (Geschwader Kommodore to July 5 1943) and his successor Major Hubertus von Bonin had victories from May 1942? This will help indicate where the Stab was assigned.
