[GreenKeys] neat ebay item

[John Poulton]

TMC built these Teletype Repeaters as well, essentially identical to the
Stelma units.  The TMC version was the "SFO".. see:

http://tmchistory.org/tmc_ssb_cats/ssb_db/tmc.ssb_103.pdf

And, note the company address at the bottom of the bulletin, 121 Spenser
Place in Mamaroneck, TMC's very first manufacturing site.  TMC was building
these at least as early as 1952.
