The one I am doing never saw combat, but it was used extensively by the Luftwaffe. Heres a brief write-up.
It was initially tested at Rechlin in the original Olive Drab paint scheme but with German markings and undersides repainted in yellow. The plane was later moved to Hannover-Wunstorf during the summer of 1944 where it was assigned to 2.Staffel of the Versuchtverband Oberbefehlshaber der Luftwaffe for demonstration purposes. It circulated between various fighter units as a practical aid in teaching how to use the Fw-190s to the best advantage in combat against P-51s. At that time the original paint finish was also stripped off, presumably to match the improved performance of bare-metal USAAF machines which appeared towards the end of the conflict.
