After Polish Defence War in September 1939 Germans captured some of Polish aircraft. The German captured only two PZL.43A - serial numbers: 1737 and 1740. The plane 1737 was handed over to Bulgaria in first half of 1940, but second plane had German national insignia and was examined in Rechlin. It was handed over to Bulgaria too, but in October 1940.

One of captured and repaired PZL.43A during in-flight tests in Mielec. It's probably an aircraft 1740 piloted by test pilot Otto Winkler. Plane had original painting but had German national insignia painted on wings.
