Description

The product is a set of replacement abrasives designed for a Hall piston pin hole hone from the 1940s manufactured by Hall Mfg Co. Specifically tailored for piston hole honing, these abrasives are meant to be a perfect fit for the Hall brand hone tool. The NOS (New Old Stock) designation suggests that these replacement abrasives are new and unused despite being manufactured several decades ago, making them a rare find for collectors or users of vintage automotive tools.
