1960s Sterling Silver Slide Rule & Tie Clip
Perfect for the dapper handyman! This wonderful tie clip not only looks good, but also is a fully functioning slide rule! It has A and D scales on the base and a C scale on the slide. The clear plastic indicator sits in a metal frame and also moves freely up and down the scales.
A similar clip can be found in the Smithsonian's National Museum of American History.
