Vintage Industrial Socket Wrench Set in Metal Tool Box

This is a heavy-duty, industrial-grade 3/4-inch drive socket wrench set housed in a vintage red enameled steel carrying case. The collection includes a primary long-handle ratchet, multiple extension bars of varying lengths, and a curated selection of large-diameter 6-point and 12-point sockets. The tools appear to be made from high-strength forged steel with a polished or chrome finish. A visible maker's mark on the main extension bar identifies it as 'WRIGHT 3405 USA', a brand known for professional-grade pneumatic and hand tools. The metal box displays significant cosmetic wear, including scattered rust, deep scratches, and finish loss consistently across the lid and base, suggesting extensive use in a workshop environment. Internally, the tools show signs of heavy use such as grease buildup, surface oxidation in the socket wells, and minor impacts on the drive ends. The set appears to date from the mid-to-late 20th century, likely between 1960 and 1980, and is characterized by its robust, oversized construction designed for high-torque mechanical applications such as automotive or heavy equipment repair. One socket features a distinctive 'CHINA' stamp, indicating a later replacement or addition to the original American-made set. Despite the surface patina and signs of age, the mechanical integrity of the ratcheting mechanism and the heavy gauge of the steel indicate high-quality craftsmanship intended for longevity.
