    I am in the process of restoring a 1939 Stromberg Master clock in a 59" tall case. It has a 6289-M self winding movement. The clock seems to be complete, except that the pendulum stick and pendulum bob are missing. The top part that attaches to the pendulum stick is present, as well as the suspension spring. I would appreciate any help here as to whether the stick should be wood or metal, and the weight of the pendulum bob. Of course I'd be amazed if I could just find one for sale, but doubting that option, I will either find or make a replacement. I know it won't be original, but at least I can get the clock running while I continue to search. Thanks in advance for any help!!

    Some pictures would be helpful. Have both a mercury pendulum and a stick and bob pendulum. Scot

    Your clock originally had a mercury pendulum. The metal piece is a leader that the pendulum was attached to. Will take some pictures of the one I have and post them.

    Thank you Scot. The pendulum leader has 2 holes near its bottom.The leader's total
    length is about 10.5" or 26.67 cm, and the max width stick it would accept would be approx. 7" or 17.78cm. Would these holes at the leaders bottom be for 2 screws that would thread directly into a metal "stick"? It will be helpful to see your pictures.
    Any ideas where I might obtain a pendulum for this great old clock?

    Thanks Scot. I just measured, and from the bottom of the pendulum leader, the pendulum should be just shy of 36"...or at least that's how much room I have to just above the beat pointer.
    So it looks like a good match. Is it one that holds actual mercury, or just 2 steel cylinders that look like mercury jars? I'd love to talk further about this pendulum. I only joined yesterday, but was an active NAWCC member in the 80's and 90's. I will create a CLOCK PARTS WANTED forum post
