Vintage PROTO 4011 Bar Type Puller Screw 4012 Three Jaw Attachment And Tim. Cup

5 piece set, includes an 11” PROTO Bar #4011, 10.5” push screw #4012, centering point, three jaw attachment and cup #1329. Does not include any jaws that slide over the bar. The three jaw attachment has no part number but has Patent USA on the body and is threaded for the push screw. I don’t know what the Tim. Cup is used for or what brand it is but it is threaded for the push screw. All parts are in good condition with normal wear and some surface corrosion.
