Interesting reading. When I was entered active USAF duty in the
mid-60's, I was schooled to be a teletype operator. The schoolhouse had
Model-15's and Model-19's.. My first assignment was in TA-land
(Turkey); the center had modern machines, Model-25's and Model-28's plus
some 15's and 19's. Those mechanical monsters were fun at 45 baud (60
wpm). When they got upgraded to 75 baud (100 wpm) we thought that was fast!

These two links have some continuing interest for hams. Newer hams
may want to find out what older hams are talking about when they
mention Teletype machines. Older ones may want to reminisce or look
up the approximate date of manufacture of machines they may have used
in past years.
I was a Radioman in the Navy in the mid-1960's. We used model 28 and
32 machines on the ship I was on during active duty.
Another interesting discussion along these lines (that also includes
discussion of the teleprinter keyboards) is found at
http://www.diycalculator.com/sp-qwerty.shtml
and it brings in the history of the keyboard and variants of it; why
we call letters "uppercase" and "lowercase"; and punched paper tapes
used in communications, among MANY other interesting and possibly
obscure facts.
