[GreenKeys] Teletype in Portable Case

[Jim Haynes]

Unfamiliar to me.  The fact that it has the Teletype logo on the front
suggests it was put together by Teletype, possibly as a trial model that
was never produced.  If some other company had repackaged a 33 they
probably would have put their own name on it.

I would assume the hold-down screws were replaced with perhaps shoulder
screws that would allow a very limited amount of motion.  Do you know
any more about it than those two pictures?
