Artillery barrels and frames

The proof firing of a firearm normally consists of firing the completed firearm with a cartridge that is loaded substantially in excess of the pressure of the cartridge that will normally be fired. When the firearm passes this firing proof, the firearm is then marked with "proof" of it's successfully passing the test firing.
I have no knowledge of what procedure was used by either DWM or Erfurt as to the proofing procedure on newly manufactured Lugers, but see no reason the procedure would differ from any other manufacturer. Possibly in the case of providing barrels for another manufacturer the barrel was proofed by the manufacturer, but this would not prevent the eventual user of the barrel from proofing the completed pistol and applying it's own proofs. For a time Winchester had a "mail order proof" on their barrels that were shipped out for installation by someone else. This identified the barrel as being proofed but as not being installed in the Winchester factory.
