[Milsurplus] manual needed - AN/UGM-11 TTY test set (a.k.a. Wavetek 404)

[Nick England]

Anyone have a manual for an AN/UGM-11 (Wavetek 404) TTY system test
set that I could buy or borrow to copy?
If you are curious, photos and some info is at http://jproc.ca/crypto/ugm11.html
I acquired one of these for a few bucks at a hamfest - it generates
AFSK tones, TTY loop, and even AN/UCC-1 multiplexer channel signals. I
got mark-space working but it isn't generating sequences (RY, FOX, and
simulated crypto gear).
Seems like none of the usual test equip. manual sources can help.
cheers,
