Hi and welcome to SRP!

I'm not really that up on Solingen blades, but I do know Dovo makes (made?) a 'Prima' razor. I would expect however that Dovo would be stamped on the tang as well as etched on the blade if that's what it was, so methinks that isn't what this one is.

Hopefully some of our resident experts on German blades will see this.

Is there any way you could go back to take some pics?
