Heavy-duty Hein-Werner "Screwball" bumper jack is made of steel with a 1.5-ton lifting capacity. This vintage mechanical jack has a screw-driven lift mechanism and an adjustable bumper cradle. It is manufactured by the Hein-Werner Corporation in Waukesha, Wisconsin. It is missing the handle but turns up and down. Would be very handy for building derby cars
