Well just to make sure the dead horse doesn't rest, here's Teletype's
TT-242/UG which was the lightweight (not necessarily light duty) prototype
that the USN declined in favor of the MITE teleprinter...

Teletype intended that the M33 machines were for light duty only and were
evidently somewhat surprised at how the 33 was adopted as the standard 24/7
computer terminal for everyone but the military.

R-390 content - all my teletype machines are hooked up to FSK converters
attached to R-390A receivers.
