[TowerTalk] Tri-Ex W-51

[Don Tucker]

Does anyone know what the difference is between the W-51 tower of old 
and the later nomenclated WT-51 - or - is it just that, a renomenclated 
tower with no physical changes?

I have a W-51 (on saw-horses) I was given a few decades back I'm looking 
at possibly using as a second tower, but the owner had no documentation 
(except for the mounting base and hole details).

All of the manuals I find on-line are WT-51.
