[GreenKeys] Reasonable motor speed for model 15/19

[Windows XD]

Dear all,

I am trying to tune my model 15/19 teletype governed motor to the correct
speed. Just to make sure my measuring equipment isn't out of spec, would it
be possible for an unadjusted teletype motor to go at 2,160 rpm? I am
measuring it with a phototachometer and it just doesn't seem like an
accurate reading.

Thanks in advance to any replies
