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 particular pistol was reworked by the Imperial Japanese Navy, with an "anchor" stamp applied to the right side near the serial number and the stock slot in the backstrap filled in. Produced by the Tokyo Gas and Electric Company under military contract, with the "GTE" marking on the chamber, model markings on the right side over the serial number and a pair of Kanji markings on the left side. Fitted with fixed front and tangent rear sights, serrated cocking piece with a replacement unnumbered knurled bolt cover, grip safety on the front strap, lanyard swivel, checkered contoured grips and a correct replacement nickel magazine with checkered aluminum base.

Very fine, with 75% of the arsenal refurbished blue finish, showing mild spotting and handling marks overall, moderate to deep pitting concentrated on the gripstraps and barrel, and mild edge wear. The grips are also very fine, with some mild dents. Mechanically fine.
