Is this Bonney a whole tool or part of a tool ?

Currently stuck.
Before I go nuts trying to break it free, figure I should probably find out what the H## it is.

Tried looking it up based on the number - got nuthin

Google says B56808 is listed in a 1967 Bonney Tool Catalog as a Ball Joint Remover, for Chrysler Ball Joint Assemblies.

How big around is a vintage ball joint?
I can barely fit my thumb into the end of this thing

you would screw that over the thread then hit with hammer to drive it out of socket. You might use the 50/50 mix of atf?acetone for a week or two  that should  loosen the nut up.
