1930s PRATT AND WHITNEY TRACER TOOL

Description

Cool piece of Pratt and Whitney history! The Keller Department was their heavy machinery division, this attachment allowed for precise reproduction of profiles from templates. Wooden box has an old style Pratt and Whitney logo, with some minor damage. Latches on box are labeled “CORBIN MADE IN USA”. Main shaft rotates by hand, as does the handle. Would need inspection and possible repair before usage on machinery. Or polish up the brass and get a cool looking steampunk piece. One end included, marked “S 3/4 X 1 1/2 S”
