John, Here are some pictures of the inside of the pendulum's cast brass shell and the discs that were inside of it. The bottom two discs are steel (one is used as the bottom cover), the next two discs are brass, and the last disc is copper. Note that the inside surface of the cast brass shell is inscribed with the movement serial number. Also, the two brass discs are stamped with the numbers 2055 and 1248. A number.40 suspension spring was put in the clock yesterday afternoon and it ran approx. 16 hours, gaining only 5 minutes, before being stopped to inspect the inside of the pendulum this morning. So it seems like it will be easy enough to get it regulated now. Thanks again for the information that you and Eric have provided. Pat L.
The time gain is essentially 1/3 of a minute per hour, or about 20 seconds per minute. Pretty fast. You will need a thinner spring on the order of 0.0035 or 0.0036 inches. Note that each 0.0001" represents about 4 seconds per minute. Kurt
Pat, Quite often extra discs are added to bring a clock in time with the suspension springs that are available. In it's original form, your pendulum would not have had any extra weight and would have had a smooth cover held in place by a lip just inside its edge. https://mb.nawcc.org/attachments/pendulum-1-jpg.273005/ Eric
John, This pendulum, 21996, is not consistent with any other Crown pendulum I've seen or recorded. The disc itself is too thick and matches the other gallery style discs in its number range. I would say this is a marriage of two pendulums. Eric
I know this is an old post, but the suspension bracket in question here was used by JUF with their "PA" and "DRP" movements, and when they started numbering their movements again. See this post: Seeking info: Urania 400-day clock with disc pendulum and this one: Jahresuhrenfabrik Angemeldet Clock Info required The highest number I've recorded with this bracket is JUF 53182.

Could anyone shed any light on this? I acquired it about 5 years ago, it looks like a Wurth but I am not sure
It is a Wurth. I also notice you have it on Ebay for sale. Shame about the condition of the dial, otherwise a good clock.
Thanks for your speedy reply. I have had so many questions and offers about it. We loved it for the dial, but We know nothing about clocks at all we just liked the aged look. Sadly we have gone for the modern look and having a 2 yo around the house it isn’t practical to have a glass dome within arms reach.
Yes, a Wurth from 1905. The dial is checked but not the worst I've seen. I could probably be carefully preserved. Wurth changed from 2" dia celluloid or enamel dials to 2.5" silvered brass dials around number 6000 so yours is one of the last in that style. Your hour hand is a good replacement. The originals were very frail and easily broken. The rest looks complete and original. Very nice! Too bad you can't keep it. Eric
I have this dial that also came with the clock.. as you can see from photos it’s a bit larger in size. It looks a little bit big for the hands but is very similar to the one that is on it
Your clock has the correct dial installed for its age and number. So far I have found no match for your other dial in my records. Eric
I have some Gustav Becker and Kienzle dials that look a lot like the script. But one of my Badische Uhrenfabrik dials appears to be an exact match...it's the same dimension as measured above. Kurt
Thanks Kurt, Now that I know where to look they're easy to spot. Your link is to a Huber clock, not Badische. The subject dial shows up in my records on numbered Hubers and Kienzle clocks. Eric
