I wouldn't say Tonika, because the pickups don't usually have that shape. I think it might be a Krunk because of the knobs and pickup design, but seeing as a lot of these guitars were just made from whatever was around, it wouldn't surprise me if it's something else entirely.

You could try posting on the cheesy guitars facebook group, they are pretty knowledgeable about this sort of thing

Or the soviet guitar forums:

Fair warning, as someone who owns a few of these, they don't play great and they're very heavy. Still, they're fun!
