Several.
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.
