[GreenKeys] Model 32 ASR with four row keyboard.

[Jim Haynes]

That certainly looks like a Telex keyboard - noting the rotary dial 
typical of a Telex machine, and the top row of keys have digits only,
and the next row having nothing above the alphabet letters.  I expect
you will find it as I described earlier, the digits row blocked when
it is in LTRS case and the next row blocked when in FIGS case.  I guess
some important customer wanted a Euro-style Telex machine from Teletype.

One other question would be the metal strip across the front of the
machine.  Those sometimes identified the service provider the machine
was associated with.  "Teletype" for generic machines, "Western Union"
for their machines, and I don't know who all else might have had
distinctive plates.
