Hi there Phil,
This is Erla built Bf 109 G-14 W.Nr. 46. ... "Gelbe 12", 3./NAGr ?, Kassel-Rothwesten, May 1945. This machine stems with high probability from a yet to be identified NAGr. unit, as indicated by the small white triangle on the top of its tail. You will find here seven other pics of this machine.
