Folsk,
Just for the sake of a close-up on one of those white wedges Bf 109 G tails, I've uploaded such a pic of Bf 109 G-14 W.Nr. 463 141 "Schwarze 17" of 2./NAG 14:

Still looking for others; there is one similar marking on a tail of a Bf 109 G in Broken Eagles 2, p. 8, taken at Lippstadt.
Will keep you posted.
Cheers
Marc
