FWIW - here's a photo of the 28RO base with tachometer. The speed meter plugged into the 1/4" jack on the front.
I understand these were useful for copying foreign RTTY.

Some Model 28 RO military TTY’s came with the LMU-10 governed

motor that could be mechanically adjusted for different speeds. This

version had a tachometer on the motor hooked to a calibrated meter so

the speed could be “dialed in”.
