An interesting forensic thread. The material is pattern welded. The quality of the etching (pattern) is pretty crude, as is the pattern itself, and not what I'd expect from Solingen. The grind is nothing like any Puma razor I've seen or handled, which tends to help me lean toward an artifake. Those of you with more razors to look at can discuss the various manufacturers marks. I have no idea if they are correct for the company, but they do not seem to match either.
