What tower is this?

[zman2893]

We have these towers on our work site, located in Hudsonville Michigan, and we are trying to figure out who the manufacturer is and where they came from because it's been 15 years since we first got them. If anyone has any ideas feel free provide information.

It's a well worn BX self supporting tower.

They were originally built/sold by Rohn, but it looks like these guys took over the design:

The wider spacing (5 per section vs 6) of the X bracing on the sections above the lowest section would indicate they are older Rohn AX sections.
