This is an excellent example of a scarce Bergmann semi-automatic pistol manufactured in Herstal Belgium and converted to the newer mechanism at a Danish Arsenal in 1921. The left barrel extension is marked "ANCIENS ETABLISSEMENTS PIEPER, HERSTAL-LIEGE, BERGMANN'S PATENT." on the left side with "BREVETE S.G.D.G." towards and "M.1910/21" below the frame rail. The right side of the barrel has the following proofs all in a row, early "Belgium Lion/PV", "crown/R", "star/B", "Belgium Perron" and "Belgium ELG" proof. The right side of the barrel extension also has the "Belgium Lion/PV" proof, "star/B" and "Perron" proofs. There is a property number or unit number (1378) on the right rear section of the frame. The serial number on the frame appears to have been restamped with the magazine serial number having been restamped. Note that the frame and magazine have the same number. Fitted with smooth grips.

Excellent overall. The pistol retains 95% original rust blued finish with minor holster type wear. It retains the original bright "in the white" polish on the hammer, trigger, magazine release, bolt and safety lever. The grips are fine with some minor handling marks. A scarce very early semi-automatic pistol.
