Sears Craftsman vintage dado cutting saw blade, 7 inch 24 tooth carbide tipped wobble blade

Sears Craftsman 'wobble blade' for dado cutting, a 24 tooth 7" blade with adjustable center to control the width by adjusting the angle of tilt.

This has some sawdust on it from years in a woodworker's shop, but doesn't really look as though it's been used - the carbides look great.
