I've got an M39 SOV copy with a Ukraine built PE scope on it. Its a great collectors piece, however it really highlights the futility of Finland in the war, as its an awkward piece to work with, generally speaking. Smashing looks, bent golf club feel. Wouldn't trade it for anything though, with that sort of character.
Come to think of it, the scoped M28/76 isn't a heck of a lot better for ergonomics. Its long eye relief optic requirement is a pain on its own. With open sights, however, it really purrs.
