[GreenKeys] Model 15 serial numbers

[COURYHOUSE at aol.com]

But  what   I  stated...
and  stated  from the beginning  before being routinely  dismissed years 
back...
was  to  start gathering sales  records  to start the  database.  Records  
containing  sales of new units  would be  the closest to the  true issue  
date. 
 
If  you  tried to build a database off  stuff that had   been out in 
service commercially  for  years, or  ham used   ttys or  deaf used  ttys the  
results  would indeed be  dreadful!  Some of  my elderly Deaf and Hard of 
Hearing   friends  told me of getting  lots of  units and  units that  were in 
pieces and  just  'making them  work'

Serial numbers on Model 15 machines seem not to be too  useful.
The motor, keyboard, typing unit, and base are all easily  
interchangeable, and the big users (WU, AT&T, news services,
the  military) often swapped those subunits in the field.
A used machine  probably doesn't have its original subunits.
Many machines also have a  property number, but that's not
manufacturing info.

There are some variations which indicate age.   Wooden
rollers on the platen and a wooden paper spool hub indicate
older  machines.
