Re: Bulle Mantel Clock needs help Thanks Eckmill. There is no sign of a hairspring or any other elecrical connection bipassing the two suspension cloths. Thats what has me puzzled. The electrical path I can see is:- back of dial support pillar - spring to fork - contact pin - brass pendulum rod - one side of coil - internal connection to other side of coil and brass cover - steel pendulum rod - ??cloth suspension - brass support post. Thanks also John - most helpful. Will look for serial number and send close- ups of movement later. There is a spring steel tab pressing on to the end of the fork arbor shaft. Is this also to stabilise the movement?
