[Towertalk] Rohn Tower??

[Jerry Keller]

I have several sections of what I think is an old Rohn tower model.
Triangular, tubular steel, 12 inches across a side, and the braces are
horizontal, about 2" wide, like ladder rungs (would be easy to climb). The
top section tapers to an 18" long tube 1.75" I.D. I guess you just grease
the tube (unless there's a way to mount a thrust bearing that I can't see)
There's a tilt-base and a round rotor shelf that mounts with u-bolts. Can
anyone ID this for me?  Jerry K3BZ
