Steve,
copy to list

I get confused between Model 15 and 14.  I guess the "14" is tape equipment like typing reperforator and 15 is page printer with our without keyboard.

I wonder what motors ran at 2100 RPM.  Seems to me that most of them are 1800 rpm but I'm not sure.

I wonder if an 1800 rpm motor would run the machine correctly or close with those gears.

18/21 x 75 =  64.3 wpm

Maybe a governed motor would be adjustable down to 60 wpm.
