[time-nuts] Chelsea Chronoquartz dividers

[Bill S]

A friend has acquired a Chelsea Clock Company Chronoquartz which was 
probably made in the 70's. He has measured the oscillator frequency at 
approximately 4.194304 MHz. He wanted to know what arrangement of 
dividers they used to run the 4 pole stepper motor to step seconds. 
Anybody know?

Thanks,
