Our Assessment: The Nambu Type B pistol, generally referred to in the West as the “Baby Nambu”, was a three-quarter sized scaled-down version of the Model 1902 (“Grandpa Nambu”). Very limited production started in 1903 with full-scale production beginning in 1909. Production continued through 1921 to 1923 (records from this period are incomplete), with all production moving to the Tokyo Gas Electric Company to free up production capacity for the modified 1902 “Papa” Nambu. The “Baby” Nambu were never adopted by any branch of the armed forces but were sold to officers through officer stores. Sales, and thus production, were limited due to the pistol’s high cost when compared to comparable import pistols which tended to not only be less expensive, but also of higher quality. This example is in quite good condition, retaining the great majority of its original finish, a decent bore, and all-matching serialized parts, including its magazine! With approximately 6,500 pistols made between the Tokyo Artillery Arsenal and TGE, this pistol is perfect for a collector of Japanese firearms. It would look great along-side its “Grandpa”, “Papa”, Type 14 and Type 94 cousins. Please see our photos and good luck!
