an RCA radio instruction booklet for a (2BX63).
The GE color TV stuff must be very rare. It is for a rectangular set with that dim blue tuning meter. A color thing goes around the knobs to instruct about the meter.
It was on eBay but if you use this item #6289016761 it would come up as "ended" but you could write to the seller and still get it. I intended to announce this earlier and got sidetracked.

I am not associated with the seller of stuff like this I post. I just imagine that if I had a nice GE set like this that I would love the little extras.
