Soon an expert will tell us for certain. So, I'm going to guess about it...
It was made/sold before '68 because of the logo. I'll guess it is from '62 up but it would not surprise me if it was from like '58 up. I think it was only available to hospitals, etc. and not to the general public. I think it is only a plastic box to hold switches and speaker. Lastly, I bet that speaker wire was added and it originally had a white thick cable for all the wires to the set and probably plugged into the wall to get to the set. Probably from some place where sick, rich people got pampered. Most hospitals back then probably did not have color.
I'm going to ask the seller where they got it from.
