I have a cobra 21 I believe and the squelch button broke off fully and I am unable to move the squelch but I don't think its unable to move I just don't know what I can use and the replacement part says its unavalible so I'm kind of stuck here
 

That is an absolutely ancient radio. Maybe time for a new one? Cobra 29 can be found on sale at many truck stops and there are lots of deals on Amazon too!
 
Hmm.

Cobra 21. A 23-channel radio. Not made since about 1976.

Cobra 21XLR. Made in 1978

Cobra 21GTL. Made in the early 1980s.

Cobra 21 Plus. Late 1980s, a real dog.

Cobra 21LTD. 1990s radio.

"Cobra 21" is a bit like "Ford Mustang". Doesn't narrow things down all that much.

Controls like those pop up on fleabay a lot.
