Since you appear to have done some research on Kittel's aircraft, you may already know that two of John Weal's books for Osprey contain color plates that claim to represent Kittel's A-6, "Yellow 5" while he was serving in 3./JG 54 circa August-September 1944. See, Focke-Wulf Fw 190 Aces of the Russian Front, p.55 and Jagdgeschwader 54 'Gruenherz,' p. 73. It is unclear what source(s) Weal used in creating the plates.
