I have a HSc with a sn of 714556. It has no proof markings on either side of the webbing by the trigger. I know nothing on the left side means commercial. But no factory proof marking on the right side? The finish is in great shape, and all engraved numbers match. the electro pen marking under the slide is different. Does anyone have any info? This is my first mauser, is it normal for it to not have the factory proof? Also i was told this was a "bring back", and it has no importer markings.
