The Amphibias have a really big variety on casebacks appart from the basic one from Vostok (Antarticka, Gagarin, Scuba Dude, Neptune, Orca, etc) and several aftermarket ones. The same doesn't happen with handwinding Komandirskies. Modern ones seems to have only the double headed eagle caseback. Vintage dirskies usually have either a plain caseback or the ray pattern caseback. Anyone knows about aftermarket casebacks for the modern handwinding Komandirskies? A bit of variety for the modern ones could be nice. I mean Komandirskie series 21, 43, 53 and 81.
