The Norwegian Kongsberg Model 1914 was a modified copy of the U.S. Model 1911 pistol used by the Norwegian army. These pistols are nearly identical to the Colt Model 1911. This Model 1914 features a slide dated "1929" on the right side. The left side of the slide is marked with the later model 1914 caliber, model, and serial number marking with the monogram of King Haakon and the Kongsberg Crest. Inspection mark behind the rear sight and below the date. Matching serial numbers found on frame, slide, mainspring housing, grip safety, magazine catch, and barrel. This pistol was likely reworked by an arsenal due to the lack of serial numbers on the safety, hammer, and slide release as well as the phosphate finish rather than blue. The trigger is numbered "365" rather than with the whole serial number. The included factory letter gives dates for proof firing, initial inspection, sighting in firing, final inspection, as well as shipping date to Royal Norwegian Navy Artillery. The serial number range which includes this pistol, marked as being sent to the Navy, is referenced on page 390 of "Kongsberg-Colten" by Karl Egil Hanevik.
