Manufactured by the Tokyo Arsenal from 1909 to 1928, the Baby Nambu was the semi-official officer's pistol of the Imperial Japanese Military; officers would privately purchase their sidearms, with the Baby Nambu presented as the local alternative to imports from firms like Colt, FN and Walther. Fixed sights, with the "stacked cannonball" arsenal marking on top of the chamber and the nomenclature markings and serial number on the right side of the frame. Fitted with checkered grips and a nickel finished, alloy base magazine. The magazine is mixed and the firing pin unnumbered, with the other components matching. Two books are included with the lot; "Hand Cannons of Imperial Japan" by Derby (which includes the S/N of this pistol on the list of known examples) and "Japanese Handguns" by Leithe.
