Description

A vintage air rifle manufactured under the Industry Brand (工字牌) in Shanghai, China. This specific model is designated B3-1, with Article Number G 6238, consistent with export models produced by the Shanghai Air Gun Factory. The rifle features a classic underlever spring-piston action, designed to fire .177 caliber (4.5mm) pellets, a standard for this model line. The construction includes a wooden stock finished in a high-gloss lacquer, paired with blued steel components for the barrel, air tube, and receiver. Markings on the metal receiver include the stylized “H” logo within a diamond, the Chinese characters 注册工字 (Registered Industry/Work), and the country of origin “MADE IN SHANGHAI, CHINA.” A specific designation or serial number, F393046, is stamped near the breech. The buttstock retains its original white caution sticker detailing safe use and noting it is a “HIGH POWER AIR GUN” dangerous “UP TO 355 YARDS.” The rifle is accompanied by its original brown cardboard shipping box, which bears the full Industry Brand labeling, model number, and confirmation of manufacture in the People’s Republic of China.
