Nomenclature Question

[19and41]

I have a couple of missing inserts of the type that are clear to cover the number on a touchtone or Trimline phone and in my case, a beige one that covers the screws on the Trimline cradle.  I can't find anything like them nor even a proper name to do an Ebay search.

Is this what you are looking for?

Looks like that seller didn't know quite what to call them either, settling for 'CLEAR  PHONE  NUMBER  CARD Retainer / Cover / Protector'.

That's the critter.

I tried using that description in a search and I drew 0 listings like my other tries.  All I come up with are plastic cased trading cards.  I know someone has a half zillion of these and they don't know what to do with them.
