CaptainPattarozzi,
I would like to thank you very much for your input!!! As you know I did not have a good feeling about the logo but lacked the information as to which maker had that specific Reichsbetrieb number to cross check it against the maker. It proves that the etching even though it�s not badly done is fake. I am very interested in the book especially if it has a chapter on the R.B. Nr.�s. By any chance is there information in it on R.B. Nr.�s for German leather goods makers?

PS: If I was the owner of one the those Voos/Olympic knives and saw this thread I think that I would be starting to get a really uneasy feeling right about now. Some of them paid some fairly high prices to own one. Regards, FP
