Spelling seems to be optional with many of the Russian texts. Naboka spells one name one way, Seidov and German another, and Pepelyayev may have a third or just use nicknames (e.g. Sasha, Fedya, Shura, etc.)
It plays hob with trying to sort out a list of pilots. I have one of over 1100 and am not too trusting of some of the names. However, the 196th is one of the best covered and most consistent.
