someone was asking recently who made the TGC-1, whether it wa
W.U. or Postal or somebody else.  I know the machines were Teletype
but don't remember who built the sets.

TGC-1 was especially a military torn tape item.  Since each cabinet
handled one or two lines send and receive it made it easy to set up
a relay center of any size.  Whereas the fixed stations preferred
a sending aisle and a receiving aisle and a routing clerk in between.
That's where you see those MXD machines with up to ten or so tape
readers.
