Yes, Ack, I got that part. I mean any potential skin request. You would ask that to any specific profile.
Here is a photo of a Merlin 64 engined Spitfire Vb of the 3rd Squadron of 57th GIAP that took part in the Kurban battle.
I can't read the Russian caption but this is supposed to be the same Spitfire pictured above. I read that the arrow on the side was painted later on but only have seen it in illustrated profiles. All photos of 538 show it with the original RAF paint scheme.
*EDIT* Actually, you can barely make out the arrow in the photograph, I guess the contrast blocks most of it out.
I know these images are from a model kit but they do show specific plane profiles.
There is enough out there to create a legitimate VVS Spitfire skin that would qualify.
Good information on this site on the Soviet Spitfires.
