In the slowly building-up of the white triangle atop the rudder marking on some late-war Bf 109's, I just found this picture:

Pilot is said to be Oskar Wehner, place is next to Fulda, date April 1945. My guess is that this is a NAGr Bf 109 G-6/R2 or G-8. An confirmation/details most welcome!
Cheers
