Of course not. And even so, it wouldn't help. That would be for
66 WPM speed.

Actually, they have a little lamp with a switch that illuminates
the spots on the the back of the motor. But then that assumes
50 Hz line frequency too. 50 Hz makes the dots stand still. To
set up the speed correctly for 60 WPM I'd need a 45 Hz tuning
fork or strobe.

I got a sneaky trick. I glued a rare earth magnet to the back of
the motor. I'll use a pick up coil and a frequency counter to set
the speed correctly.
