In collector parlance, 1920 Commercial Lugers would have been manufactured by BKIW (as DWM was renamed after being reorganized post WWI), would bear a factory serial number in the known range and possess a firing proof as applied by the government. As Dwight Gruber has pointed out, frequently there is an attempt to call a Luger that has been assembled from period parts but lacking a proper serial number range and/or firing proof a "1920 Commercial", but that, as he states, does a disservice to the Luger collector and historian...the date of fabrication of such a piece is indeterminate and could be 1920, last year or any time between.
