Western Union self-winding clock

Tony> If it is a syncronome, there are likely to be contacts for Tony> slave dials too No, those are the same contacts. A synchronome has the slave dials wired in series with the master clock contact and solenoid and the battery. That's actually a key part of the system, allowing things to keep going even if the load varies a lot, or the battery is pretty run down. paul
