The He 72 Kadett looks rather like the Fw 44 Stieglitz, but the main landing gear is very different and there is a strut supporting the tailskid. According to the German Wikipedia, He 72 production terminated in 1937 after 768 airframes, including 495 built by Fieseler. It also says that 629 Kadetts remained in Luftwaffe service in 1940, and 417 in January 1944. The Werknummer (c/n) on the tailfin looks like 426 in this and another photo but I'm not sure. It is certainly three-digit, which would indicate a Fieseler, not a Heinkel c/n. The badge belongs to Flugzeugführerschule A/B 24, which was based in Olomouc, Czechia for most of WWII.
