All I know is that it's from Germany. It's tiny until you screw all the pieces together and then it's the same size as a Gillette Tech. Any ideas?
I have a little Hoffritz version of that same razor. As far as open combs go, I find it to be pretty mild. There were a bunch of companies in post war (?) Germany that cranked out these little Old Type clone travel razors. Yours looks to be in better shape than mine. A nice thing is that if the handle is too small for you, just pop the head on something more substantial.
