    Anyone know what voltage I should try for this clock? I'm also wondering the approximate year and where to hook up the power. thanks for all your help

    Might be better to post your enquiry in 'Electric Horology' section, where experts on such questions are more easily found. It would also be better for future researchers.

    Perhaps a moderator may move this for you.

    They run on 24 volts DC. You can use one of those converters that plug into the wall. I don't know the year, but assume around the 30's.

    thanks Frank, 24V sounds about right. I have had 9-14V DC hooked up and it seems just barely enough power to wind, usually failing to wind and just making noise with the contacts trying to close. Do you have knowledge of all the manual buttons on these clocks? What are the following on the bottom inside cabinet: 1. SET KEY 2. RESET 3. WIND. I realize that the WIND button activates the wind feature, but why and when and how many times would you press this, maybe just a couple times when you first start it and it is completely unwound? The spring on this clock is very small, so I would imagine you could break it by over winding? thanks

    This style of Standard master was sold from 1913 through the 1920's. Since they were often used to control bell systems and slaves in school and factory buildings, if you can discover the provenance you should be able to get a good idea of the year of manufacture.

    This clock is from a school in Ohio that was built in 1936, is it possible that this is a 1936 clock?

    1936 seems late for it, but it may be possible. That pendulum seems short by about 10", have you had this running?

    You are correct about the pendulum, it was broken and someone shortened it. I'm currently fabricating another rod. All the electromagnetic coils seem to function, including the tape reel and self winding, can't wait to try with correct pendulum width. I wish I had a schematic or set of instructions, and the actual year. I have not been able to find anything online to help date this clock, except it shares the cabinet and components of older 1910-20's clocks, except the dials all have roman numerals. I'm guessing that since it is 24V, it would be 20's and possible into 30's, but just a guess.
