Detailed description

Vintage piston groove service tool / piston ring groove cleaner with PAT. NO. 2,109,857 clearly stamped on the blade. Patent date points to the late 1930s, though the exact production year and maker are not confirmed. This is an all-metal automotive service tool used for cleaning piston ring grooves.

This example has been cleaned, lightly oiled, and waxed to preserve the original aged finish rather than over-restore it. The mechanism remains functional, with rack teeth, pawl, selector head, and adjuster present. It shows honest age, wear, staining, oxidation, and surface patina consistent with vintage shop use. No box or paperwork is included.

A strong piece for a vintage tool collection, mechanic’s display, garage decor, or period automotive memorabilia. It can also serve as a conversation piece in an engine, machinist, or industrial themed space.

Printed care sheet included with shipment.

Ships carefully packed.
