Yes. But it is the plane of the Stab of the KG76 unit. The individual letter is of the blue what means that the full code should be AA where the "blue A" is the aircraft individual letter and then the "black A" what indicated the Stab of the Regiment (the KG 76, code F1 in the case). Because all knew the blue letter meant the KG Stab and the aircraft was the KG commander's mount, the black one could be omitted. BTW ... the Sqaudron Stabs of a Regiment had the individual letter of the green.
