Before WW1 everione wanting to build a Mauser M98 actioned rifle had to buy an action from Mauser, Oberndorf first. the Mauser patents were still valid, so more than 70% of the Commercial production was sold as "actions only" or barreled actions then. Mauser always numbered all Action parts matching, the full Serial number appearing under the receiver ring and on the back of the magazine.Rather often the Suhl or Zella-Mehlis gunmakers who then built their own rifles, with their own serial numbers added above the wood,did not care about matching Mauser numbers. But my guess here: 57822 is the real Mauser Serial number, dating the action to 1912. Apparently it remained in stock at a Suhl gunmaker until after WW1, when it was completed and barreled for the then new 7x64 Brenneke cartridge. 24482 may well be a 1920s Schmidt & Habermann, Suhl, TM Esha,serial number. S & H built all the "Original Wilhelm Brenneke, Leipzig" bolt actions for old W.B.
