That confirms that the pistol started out as a Luger that was intended for the commercial market. When pulled by the factory for military sales I believe the 7.65 mm barrel was changed out for a 9 mm. This would have also been the point at which military proof and acceptance stamps were executed, additional numbering added and PERHAPS the 1921 added. I am not as certain about the 1921 date stamp but it would make sense.
