Can Anyone Identify These Knob Inserts?
 

I have these discs, marked as being from "TV CITY" and appearing to be decorative inserts for a knob on a TV or other older electronics. Size is about 1 cm in diameter. I assume they are color TV related because of the red green blue pattern. I'm hoping someone on here will have the knowledge to at least narrow it down. Thanks for taking a look!

The appearance and part number scream "Zenith" to me....

Yes, Zenith indeed. They are not knob inserts, but rather the emblem that typically was next to the "Zenith" name on a color set that was equipped with a chromacolor CRT, so about 1970-79 chromacolor and chromacolor II sets. These would have also been used on the space command 600Z remote control (1974-79). A photo attached of a typical application of this emblem as seen on a 1972 portable Zenith color set.

Aint they also on the remotes? That's where I remembered them from...

Wow thanks for the quick responses, especially drh4683! I hope to find someone who is interested in these, they're just cardboard but I don't like to see NOS parts go to waste.

Motron, I'd be interested in those and sent you a PM. Thanks!

Cool find. The fact that practically nobody would order them
says much. Either they changed a cabinet or they took a
LOT of pride in how a set looked after a repair. The closest
thing we had were little plugs that covered a screw on mid
70's sets that had the symbol. Kids loved to pull them off
leaving an ugly hole & phillips screw showing.
Older styles went back to the roundy days. They had a white
background. After chromacolor tubes came out they got the
black background. Found on vol controls, cabinets & remotes.
Zenith supplied signs also used the same symbolism.
