I've been offered this TV. But I don't know what it is worth. Overall it is in decent shape. The CRT showed some life when connected to another receiver. The Tolex covering is in decent shape too. The big plus is the antenna and the base along with the 300 ohm twin lead.

Here some pictures:

Condition and completeness is everything and that one looks exceptional.
ten or more years ago one in that condition with all the antenna parts could bring $200 or more.

This much poorer condition one recently went for $167, probably because it was showing a raster.:

Knowing for certain the CRT was good would be a big factor in what I'd pay.

Outside of eBay I'd probably offer $125-$150 if I really wanted it.
