Manufactured by the Koishikawa (Tokyo) Arsenal from 1909 to 1928, the "Baby Nambu" was the semi-official officer's pistol of the Imperial Japanese Military. These pistols were considered quite expensive by officers at the time and were often a second choice to popular European models, leading to only about 6,000 being manufactured. The standard three-character markings in on the right of the frame over the mid-late production serial number with the "stacked cannonball" arsenal marking on top of the chamber. All of the visible numbers match, including on the magazine and grip panels. Includes a correct original, unmarked, leather holster and 14 7 mm Nambu cartridges.
