This vintage "Little Giant" screw plate set, manufactured by the Greenfield Tap and Die (GTD) Corporation in Massachusetts, USA, is a classic example of mid-20th-century American industrial craftsmanship. The set features a selection of adjustable two-piece dies, matching taps, and heavy-duty stocks housed in their original teal-painted wooden presentation box with an intact instructional label. Though the exterior of the case shows age-related wear, including scuffing and paint loss, the internal tools remain in good, functional condition with clear branding and only minor surface oxidation consistent with authentic workshop use.
