This is an excellent example of an Imperial German DWM Model 1906 First Issue, unaltered, Navy Luger pistol, one of approximately 8,000 of this model originally manufactured. These were the standard pre-World War I Navy Luger issued to the Imperial German Navy all the way through World War I and even into the Weimar era. This first issue Navy 1906 Luger has the desirable 6 inch Navy barrel, two-position 100-200 meter Navy rear sight, grip safety, and the desirable first variation safety markings with "GESICHERT" in the lower position. The majority of these first issue Navy Lugers had their safety markings modified, with this rare example being one of the very few that escaped this alteration and still retains its original safety marking in the lower position. It has all matching visible numbers, with unnumbered (possibly replacement) checkered walnut grip panels, and a Navy type magazine with nickel plated body and walnut base with concentric circles, renumbered "662" to match on bottom, along with a "crown/M" Navy proof. The top of the chamber area is undated, and the standard "DWM" logo is marked on the front toggle. The underside of the barrel is marked with a "crown/M" Navy acceptance proof with a "crown" proof on the left. The left of the barrel extension has the "crown" firing proof followed by double "crown/M" Navy acceptance proof marks. "Crown" proof mark also located on the left of the breech block. It has the standard military style serial number placement with "662a" marked on the underside of the barrel, and front of the frame, and "62" on the underside of the barrel extension. Various small parts are marked with the last two digits of the serial number. "W.K./1709" unit marking of Kiel Shipyard on the rear grip strap.
