[GreenKeys] Teletype M12 KSR

Fri Jan 23 01:37:57 EST 2015

Years back when I started hanging around on this listserv  I  mentioned  
that  a time line  tied to serial  numbers...  could be developed  if  we 
could  find  some old  invoices  with dates and sn#'s...  has anyone turned up 
any old  paperwork!!? if  we  found even some to establish  some  markers  
the  rest  would  fill in

Mine is metal and I have no  idea when it was made, though I'm happy to 
provide
details/serial  numbers/pictures if it would help determine the timeline. 
Could it be not  chronological but, say, military vs civilian?
