Am seriously interested in purchasing a torsional pendulum clock - must have all parts and the dome in good condition. And must have the winding key.
I am a watch enthusiast and would like to study the working of this clock. It doesn't matter if the clock isn't working but must be in a repairable condition. Please let me know if you are interested or let a friend who has such a clolck and willing to sell know, Thanks !!!

By the way for those not familiar this type of clock has a rotational rather than a swinging pendulum. The pendulum hangs on a fine suspension wire.

area of circle = (pi)*r*r
where,
pi=3.14
r=radius of the circle

How to arrive at this formula using the simplest method?
