[GreenKeys] Another what is it-

[Commtekman at aol.com]

Hello all-
It seems the current list topic is 'what to do' with all the tty stuff we 
have gathered up. I got into this interesting subject area late as compared to 
those of you who were more fortunate
to come on board when you could probably find a fair amount of traffic to 
copy. One of the machines that was given to me to 'haul away' is a military 
outfit with the following on it:
TT-37/GGA-1   I am wondering what model this is, and about how old it is.
Thanks for the help-
