[TowerTalk] US Towers Raising Fixture Model # Question

[larryjspammenot@teleport.com]

Several years ago, I purchased some used tower equipment. One of the items in the purchase was a brand-new (still in the shipping packaging materials) US Towers "Raising Fixture". This is the accessory unit that mounts on the tower's "T" base, on top of the concrete foundation, that lets you lower the crankup tower to an almost horizontal position. Then you can do any servicing to the antenna and tower near the ground. US Towers lists several different models of Raising Fixtures for their crankup towers in their latest catalog.

I'm trying to determine what the model number of this raising fixture is. Even though it's still unused, I don't see any model number tags on it anywhere, after taking it out of the packing materials. It's in two separate packages that were originally shipped via UPS Ground to the recipient (now an SK), who ordered it but never put it to use. The heavier/larger of the two packages contain the heavy vertical post that goes to the bottom single bolt of the "T" base, and it has the winch, cable, and pulleys. The second package has the big rods that extend to the two bolts in the "T" base, where the tower will actually tilt over. The combined weight of the two packages (including a few pounds for packaging materials) is 188 lbs. 

I don't see anything similar in current US Towers' catalogs, that correspond to a weight of 188 lbs. I see a model TRX-80HD weighing 155 lbs., and a TRX-100HD weighing 220 lbs. I believe I've even seen one more listed thats a much heavier, larger one yet, on some of the dealers' web pages. I'd like to find out which one I have, to find out if I need to order a different one that would be the correct one for one of several towers that I'm considering installing. I'm currently in the building permit planning and concrete base contractor bid process. 

If anyone has any idea what model number this unit is, please let me know. Perhaps this is a discontinued model -it was shipped from US Towers when they were in Visalia, CA (they're now in Woodlake). I don't see any date on any of the shipping tags to get an idea of its age.
