This is my new (to me) GNR, S#2002v. 1 of only 564 produced. It was a previously unreported S#. The seller stated it was all matching, except mag. When I received it Thursday, I was dissappointed to find several small parts not numbered... firing pin, hold open, rear axle pin, grip safety, thumb safety and grips.
I received Don's and Joop's new Mauser book Friday, which states these parts aren't numbered.
Needless to say, I was tickled pink.
Enjoy.
