Hi Guys, BIG TOPIC, I see.
Okay, the majority of the FAQ on grip numbering was written by Bill Munis. Bill was the most knowledgeable person on Military Mausers I have ever met. I would take his read to the bank!!
From my experience, I believe that the wooden grips on a 42 byf were numbered or numbered with waffenamt marks when they left the factory.
If the grips on present 42 byf Military Mausers are unmarked, chances are they are replacements. If they appear newer than the pistol, they are probably post war replacements. If they look like they havw been on the pistol forever, likey they are field replacements.
Anyway that's my read!! Hope this helps!!
