MiG-3, LaGG-3, Yak-3. There are at least three threes missing. Digging up useful information on them is a beast. I know some Russian and I know a native speaker or ten who can translate anything I can't. Just need to pry docs out of the archives of a hugely secretive establishment. I'm going back there this summer, but nobody at the ministry of defense has heard of a Freedom of Information Act request.
