I found a rotator in some of my silent-key father's stuff and I'm trying
to identify it. There is no control box (yet ... it may still be around
here someplace) and if I can't find it I'll want to try to buy another one.

The first one shows the rotator sitting next to a plastic gallon milk jug,
for size comparison.

The rest show different views of the rotator.

It looks like maybe a Ham-M or Ham-IV, but my dad also had one of those US
Towers crank-up masts, where the whole mast gets rotated, and it seems he
had a Tailtwister to turn that ... but this doesn't look big enough to be
a Tailtwister.

Any ideas what it might be and where I can get a control box for it?

Thanks...
