Original last series MiG-21bis grey HuAF paintscheme, right from 1979 October, from the factory. I am one of the owner of the bort No 41 aircarft from the museum and actively participated in the restoration work. The paintscheme is slightly different than the officially available "HuAF grey" from the DCS, which is also correct, but based on the first, the 1975 batch MiG-21bis fleet.
