This video showcases the rare German Haeussler patent pistol, developed around 1915 by Adlerwaffenwerke. While resembling a Luger P08, it features distinct design elements like a Borchardt C-93-inspired rear hump and a simpler blowback operation instead of the Luger's toggle system. Chambered in a proprietary 7.25mm cartridge, it was intended as an improvement over the Luger. The video highlights its unique features, including the operating handle, rear sight, magazine release, thumb safety, and the eagle relief on the grips. Despite its rarity and interesting design, estimated production was only around 100 units, with ammunition production likely hampered by WWI. The example shown is in good condition with approximately 75% of its original finish.
The Adler is an exceptionally rare early German semi-automatic pistol, produced in limited numbers between 1906-1907. Chambered in a proprietary 7.25mm Adler cartridge, it operates via a straight blowback mechanism and features a detachable 8-round magazine. Despite its unique design and comfortable grip angle, it failed commercially due to market competition and lack of modern marketing.
