Produced in limited quantities, the "Papa" Nambu was the predecessor to the Nambu Pistol, so nicknamed for being 1 generation ahead from the Type 14 Nambu, Imperial Japan's usage of this sidearm continued through World War II. This example was originally made with a slotted backstrap, which has since been filled in. Produced by the Tokyo Gas and Electric Company under military contract, with the "GTE" marking on the chamber, model markings and an "anchor" stamp on the right side around the serial number and a pair of Kanji markings on the left side. Fitted with fixed front and tangent rear sights, serrated cocking piece, grip safety on the front strap, lanyard swivel, checkered contoured grips and a nickel plated magazine with checkered aluminum base.

Very good, with 70% of the original blue finish, showing pitting (possibly salt water corrosion) on the gripstraps and grip safety, areas of brown patina, spotting and handling marks. The bolt is numbered "584", one digit off, close enough to potentially be an accidental field/arsenal swap, the magazine is mixed, with the other components (including the grips) matching. The grips are very good, with mild scuffs and dents. Mechanically excellent.
