[GreenKeys] tape printer survey

[Don Robert House]

Gil,
Here are my responses to your questions:

1)  a Western Union Simplex Printer 2-B, made by Morkrum- 
Kleinschmidt).  It takes 5/16" tape.
I had seven of the above units at one time.  All were M-K except one  
that was identical but read "Teletype"  all used 5/16" tape (all of  
it was gummed) all were Western Union.

2)  a Western Union version of the model 31, which also uses 5/16"  
tape.  - The museum has one and it does use 5/16" tape
3)  a Teletype Corp. version of the model 31, which uses 3/8" tape. -  
The museum has one of these and it uses 3/8" tape.

4)  an unusual Teletype Corp. tape printer version of the model 28  
typing reperf mechanism (which does not perf, of course);  this also  
uses 3/8" tape
The museum has a Teletype model 400 "Ticker" that uses 1/2" tape.   
The museum also has a M28 KTP which uses 3/8" tape.  Also have a  
M35KTP that uses 7/8" or 1" tape.

I know there are one or two military versions of the model 31 out  
there -- what tape do they use?   What about power?
The military M31 the museum has uses 3/8" tape and is powered by  
120vac.  It has three gear sets inside for 60, 75, or 100 wpm.
I am told there are some aircraft versions that were powered by 28 vdc.
