    hi all,
    recently I've got some clock parts in a convolute, including this disc pendulum.
    The gallery looks familiar but the adjustment weights appear unusual, as they are attached by scews on top which keeps them in place after shifting. there's no threaded rod as usual. also the diameter of the disc is rather small (about 7cm) and made of solid turned brass. Could anyone tell me, if it's original in this combination and -if so- where it belongs to?
    thanks in adance

    It is a pendulum for Jahresuhrenfabrik clock (serial 105000 up to around 140000)
    But someone reinvented the regulation rod :)

    Here is another example:

    ID needed please on this 400 day clock

    My records have 13 JUF examples in Kamil's serial number range. I had not noticed this pendulum before, and it's another one not shown in the repair guide.
