Very good. Do you notice the painted numbers under the wings on both sides, right 31019/1 and left 019/3611 possibly, and appears 317 wingtip ??
Handpainted Crosses with NOT entierly straight lines. The details most Museums always ignore and spray straigt (tape / masked) . Seen a few of them in USA and UK recently.
Link full size .... Bf 109 G-6 (hope got that correct) W.Nr. 15270 Yellow 14+- (per RAF AI2G "Details of Captured Enemy Aircraft in Sicily List 2" P.18) and was too good to pass it when it came out of Photograhic Container (Plain language: Box) at my archive desk recently. My camera entierly to blame.
