Jim,
You are right it certainly could be a clone tower. This was formerly a
Loran tower and probably purchased for the government on a lowest cost
basis. I would certainly like to think that it a clone and was manufactured
to a lower spec. It looks like a swaged reduction but the reduction is very
sharp. I compared it with some other R25 tower sections and they have a
tapered swag. I cut another leg off the tower section and posted a couple
of pics:
