freewheels and threaded hubs....

No, because they didn't have a detent lock nut as is evident from
the mashed removal slot in the retaining nut. Lotta force and
pounding!

What do you mean by detent lock nut? The splines between it and the
tool?

Look at the picture with the "freehub" dismantled. A detent locknut
requires no such extreme force. It just clicks into place and stays
there. Of course today these lock nuts are used to hold the sprockets
on the cassette hub rather than the freewheel mechanism AND
sprocket(s) onto the hub as this old unit did.
