In 97% mint sharp condition, we have a very scarce & rarely seen Imperial German World War One Military Occupation Production M1910 Bergman Bayard Pistol. This pistol is in the known serial range for the production of these pistols (151K-167k) and they bear no Liege or other Belgium proofs which is the other feature of these pistols.
They are extremely scarce and Jan Still only noted 6 known examples in this Central Powers Pistols Book. These pistols were sold to officers, and some are known to have been issued to Machine Gun Companies. If you are a serious collector of German used handguns of the WW1 era, this is a very rare find, we get one maybe every 5 years or so.
