Extremely rare and unusually designed semi-automatic pistol. Adapted for 7.25mm Adler cartridge. Striker-fired blowback pistol, with 3.4" barrel. Single-column magazine has 8-round capacity. Weight about 24 oz. Produced in a very limited number. Probably only a few hundred between 1906 and 1907. Value is speculative due to rarity. Few known sales.
