Hiya Webmaster Sir, thank you for the welcome.
I've been entirely unsuccessful in finding any such system in use in Russia during the cold war period...it seems that everyone else had some sort of standard (F.S being the obvious one) but not the Russians. In discussions with a friend of mine in USAF intelligence it seems that they never did, which seems very odd as they had a sort of system during WWII but after that it all just goes very murky.
The FS codes for the paints are a bit off, especially the Sand and Light Blue/grey, they don't look much like the photo's I've seen of the real aircraft. It's going to be mix and match job for them, but I really wnated to know about their standardisation of such things...ho hum, I'm sure something will come up in the end.
Thanks again and keep up the good work.
