[GreenKeys] Does anyone know what this is?

Gary,

Now the old gears are working.  Those radios were used by the Bell  
System in the old days to connect utility companies and municipalities  
to the telephone network via an operator.
These radios predated the MTS, IMTS, AMPS, and Cellular.  In Chicago  
they were in use longer than normal for the Chicago Fire and Police  
boats on the Chicago River.
Have you ever seen a fire boat pump water?  It is a sight to behold.

It looks like a mobile LMR receiver.  There is a PL-259 antenna  
connector on the front.  The channel crystal is in the lower right  
corner on top of the chassis.  The large open area in the middle of  
the left side would be for a vibrator power supply.

This looks similar to the GE Pre-Prog radios that we got from the  
local power company back when I first got my ham license.  We  
converted them to 6M FM on 52.525MHz.  They were used by the power  
company,  but I recall many of them being marked "Bell System".  I do  
not recall what they had to do with the phone company.

Can you see any manufacturer label?  Although it looks similar to the  
GE it may be a different manufacturer (RCA maybe).

Nothing to do with Teletype.
