VERY strange '60s ESCO reflector on craigslist

Telescope by ESCO--$100
"This telescope is from the 1960s. Very large. Approximately 6 feet tall. In two parts. Don't know if it works or if all the parts are still there. Comes with original instruction booklet...."
After glancing at the intriguing photos of this collectible telescope, I came to the conclusion that it is probably a 6-inch f/10. The tube assembly is of a truss-tube design, and the mounting appears to be a counterweighted altazimuth. WHAT IS THIS? From memory I can recall some other telescope manufacturers using the same open-tube type of design, but with larger diameter mirrors. Comments? Great photos for that vintage telescope archive. [NOTE: I know nothing about this telescope other than seeing the advertisement on craigslist. I am not the seller of the telescope.]

Seller told me that there are no scratches or coating bits missing on the mirrors- he got this from an estate sale and the place was immaculate- there is a small amount of dust on the primary. Counterweight on the mount- altazimuth apparently.
I inquired as to whether the rods making up the tube were short pieces that could undone- turns out they are single long pieces with threading. So no breakdown on this one, folks.
Seller is adamant about not shipping this scope, or even driving it out to NJ- he had it sticking out the back of his hatchback just to get it home. Since I don't even have the right vehicle it would be a hassle.
As for the quality of the optics I don't have a clue-neither does he. But I would have to think since this managed to survive 40+ years it couldn't be TOO terrible.
I've only seen structures like this for sale twice in the past two years, both on ebay. I'll have to think about this one....
