Produced in limited quantities, the 1902 "Grandpa" Nambu was the introductory model of the Nambu Pistol, so nicknamed for being 2 generations ahead from the Type 14 Nambu, Imperial Japan's usage of this sidearm continued through World War II. 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 knurled bolt cover, grip safety on the front strap, lanyard swivel, checkered contoured grips and a matching re-numbered (plus ".") nickel magazine with checkered aluminum base. Matching numbers are present on multiple components, including the bolt, cocking piece and grips.

Very fine, with 75% plus of the original blue finish, showing mild spotting overall, deeper on the grip straps and the upper left side of the frame, bright edge wear and scattered handling marks. About half of the straw finish remains on the trigger, having darkened to a mustard tone. The grips are fine, with some mild chips and dents. Mechanically excellent.
