vintage metal combination wrench marked 15/16

This is a vintage metal combination wrench featuring an open-ended jaw on one side and a 12-point box-ended ring on the other, designed for mechanical and automotive tasks. The tool exhibits a metallic, silver-toned finish with a raised central rib running along the length of the handle for added structural rigidity and grip. Several stamped markings and numbers are directly visible on the surface: the open end is stamped with '15/16', the upper handle bears the number '63 130', the middle handle states 'MADE IN U.S.A.', and the lower handle near the box end repeats '15/16'. The tool displays visible condition issues including minor surface oxidation, scattered rust spots, and general wear and scuffing consistent with age and prior use in a workshop environment. The owner-supplied context notes this as a 'Waco wrench 15/16”', but this specific maker's name is not explicitly stamped on the visible surfaces in the image, rendering the user-attributed brand unverified by physical inspection alone. The style and construction appear consistent with mid-20th-century American-made industrial hand tools, though a precise manufacturing date or maker cannot be unconditionally established without further expert analysis.

Based on what I can see in the photograph, this is a vintage metal combination wrench featuring a 15/16-inch open end and a 12-point box end, with stamped numerical markings including '63 130' and 'MADE IN U.S.A.' along the handle. I cannot verify the maker from the photo alone; the owner identifies this as a 'Waco wrench 15/16”', but this specific brand is not visibly stamped on the surfaces shown. Therefore, this estimate assumes the owner's attribution is correct. The tool exhibits visible condition issues, including minor surface oxidation, scattered rust spots, and general wear consistent with prior workshop use. My value estimate range for an item of this type, assuming the attributed brand and mid-20th-century American manufacture are correct, is $10 to $25. Market demand for common vintage industrial hand tools is generally modest, as they are often collected by hobbyists and users rather than high-end investors. If the tool turns out to be a different unbranded maker, a generic reproduction, or unattributed, the value would likely drop to the lower end or under $10, driven solely by scrap or basic utilitarian utility. To fully evaluate and authenticate this piece, an in-person physical inspection by a vintage tool expert would be necessary to closely examine the stampings, metallurgical composition, and exact pattern consistency.
