Nice score!!!
Is the OT unit salvageable? If so, do you have a torch? Can heat up the large “nut”, thumbscrew, and handle. Then hold an ice cube on thumbscrew & handle (near nut). Parts should contract faster than nut. Spray with WD & let sit for day. If it’s not salvageable, I’d just cut the handle rod flush with the nut (both sides). Little bit of light tapping & it’ll pop right out.
