Transition from Code 42 to byf

[Frank]

Jeff, the addition of "P.08" on the frame began on January 1, 1941, but the code change from "42" to "byf" occurred about February 1, 1941 . Mauser was allowed to use frames left over from the 1940 production, that weren't marked with "P.08". So a few 41 Code 42 Lugers didn't have the "P.08" Frames.

Hope this helps!
