Antique J.M. Carpenter Radio Tap & Die Set No. T.CO. 4 Sizes ASME

Rare antique 'Radio Tap and Die Set' No. T.CO. made by J.M. Carpenter, marketed specifically for cutting threads on machine screws used in radio equipment. This fascinating early 20th century tool set dates likely from the 1920s - 1930s during the golden age of home radio building and repair. The set includes 4 dies and multiple taps covering sizes: 4x36, 6x32, 8x32, and 10x24, all ASME standard. Contents are housed in fitted wooden block inserts inside a black leatherette-covered hinged metal case with a ball-stud closure. The die wrench/holder is present and loaded with an 8x32 die. Condition: The case shows significant age-related wear - the exterior leatherette is darkened and worn, and the interior wooden block has staining, darkening, and one empty die slot (one die appears missing based on the empty recess visible in photos). The taps and dies themselves show surface oxidation/patina consistent with age but appear structurally intact. The original paper label inside the lid is intact and highly legible, adding significant collector appeal. This is a true piece of early American radio and tool history - scarce and collectible for antique tool collectors, radio history enthusiasts, and early technology collectors.
