[TowerTalk] Hallicrafters / Radio Industries Rotor - Manual?

[Richard Thorne]

I picked up a Radio Industries Rotor (a subsidy of Hallicrafters) over 
the weekend.

Interesting design.  It has 3 all thread posts coming out of it at 120 
degrees around the rotor each of which clamps onto tower leg.  A 
traditional rotor plate is not required.  It looks to be designed for 
25g size tower but may be modified for 45g by lengthening the all thread 
mounts.

Does anyone happen to have a manual or a know anything about it?

I have pictures available.
