Corresponding questions need to be answered about authorized rebarrelling practices. At what level was barrel removal and replacement accomplished--field repair level? armory? some intermediate repair depot? The power-proofing procedures presented in G�¶rtz & Bryans (p.119) for replaced barrels imply that this was an armory-level repair. Were replaced barrels stamped with serial numbers to match the weapon? Are there regulations extant which detail these specifications?
The example below is a 1936 S/42, a suspected re-barrel. Evidence is beginning to appear which calls into question such suspicions based solely on witness marks as pictured. What other visible characteristics might support it as authentic or rebarrel? I certainly wonder about the way the serial number is stamped. The right side of the barrel does bear the same Mauser acceptance eagle (Costanzo, p.114, mark 176) as the receiver.
