This is a long shot, but who knows what might be squirreled away in someone's garage.

I am hooking up an AN/UCC-1C tone multiplex system for teletype connections between two rooms.
I have plenty of CV-1920A/UCC-1C receive modules, but only eight KY-558A/UCC-1C tone keyers so I can only run 4 duplex teletype channels. I'd like to find more keyers so I can run more duplex channels.
If you have any of these KY-558A/UCC-1C modules please let me know -
The cabinet with modules installed looks like this -

and a typical module looks like this

This system uses 85Hz shift channels spaced 170 Hz apart.
The center frequencies are shown in this block diagram

I could also use AN/FCC-3 narrow shift transmitter modules

or KY-346/UGC (Tele-Signal 101A) transmitter modules

If you are curious, more info on the UCC-1 is here
