Sold for: $40
Description
A specialized heavy-duty manual press or mechanical tool assembly of unknown manufacturer. The main body is constructed of heavy cast iron or steel, retaining remnants of a dark industrial finish. The tool operates via a long, bare steel operating rod/handle, suggesting a high-leverage application for forming, crimping, or specialized assembly work. The primary identifying mark is the cast inscription “PATENT 1933940” visible on the side of the main housing, which corresponds to a US patent granted in 1933. The lot includes four separate machined cylindrical steel accessories, likely specialized dies or internal components, featuring channels and pin holes designed for specific operations. The overall design suggests use in an industrial, mechanical, or possibly specialized automotive setting, dating the item to the mid-20th century or earlier.
