Not baffling at all, Mark. All the Creed teleprinters I've seen have a 
mechanical implementation of the idle line timer. On the Model 7 the 
motor winds a little weight up until it operates a switch that turns the 
motor off. It's held up by a latch that's released as soon as a space 
signal comes in. The weight drops and turns the switch back on to start 
the motor.
