This is an exceptional, extremely low serial number (150) Japanese Model 1902 Nambu or easily referred to under the collector term; Grandpa Nambu. There were approximately 2350 recorded Model 1902 Nambu pistols manufactured between 1903 and 1906, before this design was changed to the later Papa Nambu series. This specific pistol is scarce because of the serial number which is "150" would probably indicate that it was assembled in the first few weeks of production. This pistol was produced under the Army contract at the Tokyo Arsenal and is so marked with the four intertwined cannon balls on top of the chamber area. The right side of the upper receiver has the three small Kanji markings over the serial number "150". These pistols are equipped with adjustable tangent type rear sight on top calibrated from 100- 500 meters and a fixed inverted "v" front sight. They have a slot in the back of the pistol grip as they were originally issued with a telescoping wooden holster/stock. This feature was eliminated on the later Papa Nambu. This pistol has the early very small trigger guard with the grip safety on the front grip strap, the early style magazine release with the exposed spring and the arrow markings on the face of the button. It has the early style separate locking lug on the under side of the bolt, (both correctly numbered 150). It has the early style original firing pin and retainer both correctly numbered "150". The grips are the original checkered hardwood versions with both correctly numbered "150" on the back sides. It is complete with the original matching nickel plated "Grandpa" magazine with the large wooden base with the checkered edges. The spine of the magazine body is numbered "150". It has its original rust blue finish overall with the trigger, magazine release button and locking bolt retainer, straw colored and the extractor and bolt are finished bright.

Excellent with 90% plus of the slightly faded original blue finish overall with some minor edge and high spot wear overall with some light brown spotting on the grip straps. There is a small area of pitting on the very front edge of the recoil spring housing that has browned out. The grips are also in excellent condition with nice sharp distinct checkering overall with some minor flat spots on the tops of some of the checkered diamonds. The magazine as noted is original and matching to the pistol however the wooden base has a crack through the front edge (could be easily repaired by a professional). The pistol overall has all matching numbers and is truly one of the best Japanese Model 1902 Grandpa Nambu pistols we have ever offered for sale.
