[GreenKeys] Interesting cipher machine.

[Jerry Murphy]

The interesting thing in that video is that the keyboard and strip printer is a repackaged
Model 31 Teletype machine.  By the way, Teletype Corporation manufactured most if not
all of the mechanical crypto machines used by the United States.  Attached is a picture
showing a SIGABA machine on the left and the AFSAM-4 machine on the right.

Thanks for that link, Michael -
I see that the NSA/NCM artifacts channel seems to have other interesting
videos too.
