Very nice floor porthole!
Last one I saw like that was about 25 years ago in the attic of a customer that wanted me to look at it. I did check it over, and it obviously needed recapping. My quote got a "no, thanks" from him, but the interesting thing was that there was a dearth of ouchlets up there, and the big ol' bear of a guy simply placed his hands on either side of that set, and lifted and carried it toward the sole power source up there as if the set were made of styrofoam.
