[GreenKeys] Re: Teletype Models

[Don Robert House]

Thanks for contributing this Dan .  It confirms some of my 
information on the M26.  The problem is the authors did some assuming 
of their own.  They have the machine operating backwards.  The platen 
moves on a 26 --- NOT the carriage... Also the machine does not use a 
typewheel.  It is a type cylinder with the print hammer inside the 
cylinder.  You can't believe everything you read I guess.

If I were to take the model 26 and change it to model 32 the text 
would be perfectly accurate.  In 1963 Teletype developed the TT-242 
for the U.S. Navy but lost the contract to the MITE.  It was the 
machine that led to the M32 and M33.  Our museum is lucky enough to 
have two of the 50 made for testing along with the masters for the 
technical manual.  A very lucky buy on ebaY for $15.00 plus shipping.

AND NOW the BIG question,  what the heck is a Model 21 ?
