I need a pendulum for this Japy Freres. I'm only showing the movement of this clock, as it's not all put together, but is numbered.

#318 6 inches? Probably not 6 inches. Any of the clock parts supply firms will sell you a pendulum for a French clock. Adjust the length to bring clock to time correctly. Don't forget the movement needs to be disassembled and cleaned then oiled to run properly. Spraying with WD40 is not an overhaul. Or carburettor cleaner or your uncles bug spray. Good luck............
Go to Timesavers.com and do a search on French Pendulum. You'll see small, medium and large diameter examples. Measure the distance between the bottom of your suspension spring and the bottom of your clock case. Your pendulum should be slightly shorter than that with a wide range of adjustment (threaded rod). As slackjack stated, you'll need to adjust by trial and error until you get the clock running accurately within a few minutes per week. It's hard to tell from your photo but your clock probably also has a through-the-dial regulator arbor. If present, this allows you to "tweak" the timing of your clock without having to make further adjustments to the pendulum setting. If it is present, you should have a double-ended key. The smaller end of the key is used to regulate the clock in this way. Don't ever force said regulator arbor or you may strip the little brass gears involved. Also as slackjack mentions, your movement probably needs to be serviced. I see a lot of rust so it may have been stored in a humid environment. If there is any rust going on inside the movement, it could case rapid wear and tear if you put the clock back into use without having it properly serviced first. Like any machine with many moving parts, it needs regular maintenance to keep it running for another century. Have fun and enjoy your antique.
This looks almost exact to the one I have posted trying to date. One clock site I posted it on I was told that without the Grand Medaille d'Honneur symbol then this would have been pre 1860. Nobody contradicted that statement and I wonder if anyone here cares to comment? Any input is appreciated, positive or negative.
