I don't recall if this was said or not. But, For Jan 2010 thru July 2010 the Gerald Ford Museum in Grand Rapids, Michigan is putting on a Cold War Exhibit. Part of this display will be Civil Defense Items, including a Thunderbolt head.
The museum originally asked Eric Green about one, but he was nice enough to point them in my direction. (thanks Eric)
Anyway, I've been redoing the head for the last few months.
This is not a full redo. The rotator is locked, gearbox and rotator motor are removed, and chopper motor is not there either.
They have the pipe mount, so they can fab up a mount for it.
And here are the pic's(I didn't take alot of pic's or the repainting, just the reassembly).
This head has some flaws, but it's come along nicely.
