Re: Barrel number x82 or x83??
mm,
The numbers are the actual gauging of the barrel lands and groove. I don't remember off hand what the allowable tolerances are without looking up the info at home, but I feel that any of the bore gauges are accurate enough that most people could not tell the difference. This practice was stopped in late 1941 and all the 1942 Lugers I have seen don't have the gauge stamp. Appearently, Mauser could hold the tolerance close enough that the Heereswaffenamt dropped this added check. Plus, the Luger was in the process of being dropped in favor of the P.38.
