Bulgarian Luger sn 3877 with holster.  These are rare and saw a lot of combat.  This one shows it's history.  Nice holster.  Non matching mag.  This is a rare Bulgarian luger, manufactured by DWM between 1908 and 1910. There were exactly 10,000 of these pistols ordered by Bulgaria from DWM. These are a very difficult example to obtain in original unaltered condition as they saw heavy use in both WWI and WW2; having been rebuilt at least once or twice by DWM. After WW2 most of them were captured by the Russians. Crest on the toggle. he right side of the barrel extension is stamped with a single "Bulgarian Rampant Lion" acceptance/proof mark with no other acceptance proofs. The lower safety lever area is marked "FIRE" and the left side of the extractor is marked "LOADED" both in Cyrillic lettering. The pistol frame has the distinctive Bulgarian lanyard loop on the bottom of the rear grip strap.  https://www.lugerforums.com/threads/1908-bulgarian-luger-sn-3877.172/#post-172
