    Always something ... and I suppose, always something new to learn.

    Been working on a fairly original Bulle - runs nicely on the stand.

    And then I went to button it up, and the whole movement assembly was way off level, to the point of the EM hits the iron core. Huh?

    And then I look at the feet of the case - two different thicknesses front to back.

    They look old enough but have no idea if this was a purposeful tilt from the factory, or someone's way of dealing with a silk suspension issue in the past.

    Not sure if I'm going to level the case or re-tilt the whole movement structure to counter the case tilt.

    Actually, the more I look at it, I think some ground the feet down to make the clock sit level on an unlevel surface.

    And then I notice some holes from a 3rd foot in some prior incarnation.

    The things that happen to these clocks over time ...

    Mopy, the two thicker feet should be at the front of the case and there should be an adjustable brass post in the hole near the back center that is used to level the clock from to back. Have seen a number of these made that way, the two "buttons" at the back are for appearance only.

    Hi John,

    Am I glad that you replied with that info. I received the clock mostly disassembled (a bag of parts). I recognized virtually all the parts (and knew where to use them during reassembly) except for the one shown below.

    I suspect that this is the adjustable 3rd leg that you are speaking of!

    And its interesting to know that the rear feet are faux feet.

    Thank you for the info - I learn something new every time I come to this website,

    Peter

    Yep, that's the adjusting leg. Originally the short stub had a hard rubber "button" on it to avoid scratching a table top. The long threaded end should screw into a fixed "nut" set in the case, but sometimes those are missing. If yours isn't there you can make one, not difficult if you can find a couple of hex nuts that match the thread pitch and diameter.
