I've got one in the metal case.  On the back is a property tag:

Teledyne Ryan Aeronautical
E.T. "028400a"  [<- the 'a' in pen]
Gov't I.D. "MDA9729530013"
Prop. of "USAF"

Where the stuff in quotes is from a typewriter, the rest is form
boilerplate.  There are also some inventory control stickers from 1999 and

I made a new EPROM that made it output a unique code for each key, but I'd
have to dig up the notes to say anything useful.  I never figured out what
the daughter board was for and just removed it.
