[TowerTalk] tower identification

[Jim Hoge]

Greetings,
 
Any idea on the manufacturer and model of the following described tower? 
 
Circa 35 yr.s old and almost identical dimensions and weight as Rohn 45G. Leg gage the same. The big difference is in the bracing, rather than zigzag, it is a ladder style with channel steel 1" wide by 1 1/2" tall and spaced 15'' on center apart from each other. The top is a steeple design with bearings at both the top and bottom of the steeple. The rotor plate is a round plate and drilled/cut for a Hygain rotor. The guy brackets come together in the center of the tower and have attached torque arms. The section bolt holes are drilled for 5/16" and 7/16" bolts. Original galvanizing was very thick and tower surface was described as being like a rasp. This is the second tower I have come across in NTX like this.
 
Thanks,
Jim W5QM
