[TowerTalk] What is this tower?

[dw]

I couple of years ago I picked up a used tower that I've not seen
anywhere.
The material looks like 3/8" steel rod welded together.
Triangular shape with each side being about 12" wide.
Each section is 10 feet with welded flanges that bolt to the adjoining
section.
It looks like it might have been designed for a TV antenna or perhaps a
light weight vertical.
But I've not seen anything like it in the tower advertisements.
Got any guess what it is?

Thanks
