As referenced in Jan Still's Central Powers Pistols, there were only about 1,500 of these produced, with serials from 1-1500.  These Lugers are rarely seen today as they saw heavy use throughout both World Wars, with many captured by the Soviets that never resurfaced. Most of these were refinished, reworked, and/or rechambered to 9 mm during their service lives. This model has the Bulgarian Crest marked chamber area with the DWM monogram on the front toggle with Cyrillic safety and extractor markings. The full serial number is located on the front of the receiver and the underside of the barrel with the partial serial number "57" stamped on most of the various other parts, with the grips unnumbered. It is fitted with blade and notch sights, checkered walnut grips, and a correct pattern, unmarked, nickeled magazine with a walnut base.
