Hello
I recently purchased this 2 weight movement on EBay. Just the movement, no pulleys, no weights, no pendulum.
What can you good people tell me about this movement.?
I counted the Teeth and Leaves on Escape, 3Rd, and Center Wheel to get calculated BPM and pendulum length. Unless I messed it up, the BPM is 81 BPM and pendulum length is 21.51".
Numbers on plate are: 104828 just below A.Willmann & Co. on one plate
Then 28 at bottom of other plate
Please note in pic 293 a small plate with screw which is over the Speed Fan bushing. Is that to control the strike speed via screw pressure on the pinion? If so, is that common?
I want to build a case that might represent those of this movements era (my interpretation).
Too many questions??
Thanks

We have a thread dedicated to A. Willmann clocks.

I want to build a case that might represent those of this movements era (my interpretation).
Perhaps the thread on Willmann could assist you in your quest to build a case for your clock.

Regards.
