Hello, This is strange, Crimea_River, as the older people of the village told us that this crash site is the one of a German fighter shot down on May 27, 1944. On that specific day, there were Bf-109 and Fw-190 engaged against B-17s protected by P-51s. The locals do not know which type of German fighter crashed in their village. The last digit of the Fl number can be red "8" or "9 ". Which one did you use to state that this instrument is a 1915 one ? Fl. 204948 or Fl. 204949 ? Best Daniel
