I realize this is an old thread, but I don't know that the meaning of this marking is fully understood and interpreted correctly yet or not. It certainly does not seem to be unique to Mauser. And if it is an abbreviation in German, I would like to know what the actual translation is. I don't think they would have used the English word "revision" and abbreviated that? Does anyone have any further information or documentation on this? Who is the peson that Buxton refers to in his correction that did the actual interview and research? A verifiable source would be nice. Here is a link back to the P.38 forum where a similar discussion is taking place:
