X RAY, the Soviets have been producing PPK suits (G-suit trousers, much like the western ones) since the late 60's, but I have no idea why they preffered the high altitude VKK suits. The PPK suits were more common (and liked) in the rest of the Eastern bloc.
Part 2 - modern Russian pilots - 90's until today, including Su-33 pilots in orange water resistant VMSK suits. No ZSh-9/90 helmets though.
Part 3 - some early Soviet pilots wearing leather helmets. I'll probably use the stock pilot model, because the WWII pilot isn't very skin friendly.
VPAF pilots pack - Vietnam war era and modern VPAF pilots. I have to guess the colour of the flightsuits used during the Vietnam war, due to a lack of colour reference photos.
