I think that's an old Tri-Ex tower. I Have a Tri-Ex LM470D which looks
very similar....the tower sections are almost identical, but the
winch, motor mount, and control box are somewhat different. I don't
know what the A, B, and C versions looked like. I have restored the
LM470D, including remote controlling it in the shack, and it's a good
tower. I could copy the manual for you if you'll cover my costs. Let
me know if you need more info.

I recently purchased an old crank-up motor driven 60 foot tower that I
would hope someone could id for me. The motor belt drives a gearbox,
which turns the cable pulley. It has a approximately 1 foot by 18
inch control box which has two high current relays and two glass
contained relays. The glass-contained relays are in old 8 pin tube
sockets.

The tower, itself, is in good shape. I would like to re-build the
control circuits and out the tower in service. Any information anyone
can give me on this tower will be greatly appreciated. See at

It's a little difficult to tell for sure from the photo, but that
tower looks exactly like mine. The whole structure appears to be
exactly the same. It even looks like you have the same tri-bander,
stuck in the middle of the tower.

I don't have the motor on mine, but I secured a large nut on mine so
I can crank it up manually or with a socket in my portable drill.
Anyway, I don't have the data on the tower immediately available, but
I will look it up in the next few days, if you are interested. I
seem to remember that there was some information on the motor drive
unit. Not much, but there may be a manufacturer's name that would help.

This will give me a chance to try out my new scanner.
