Hmmm. It definitely looks like a gillette tech head. The handle looks European. My merkur 1906 has a similar handle, with knurling where this one is blank. My guess is it's a mismatch. I've never seen a gillette handle that looks like that.
The handle has a rustic look to it, which makes me think it was from a less advanced factory or workshop. It makes me think it was made in a poorer country, maybe Russia or Eastern Bloc. But that's just a guess.
