Don't know much about this clock. Found it in a box when I was moving friends parents. They had a lot of porcelain and China from France in the box with it from the early 1900's. Might be french???? It is beautiful. Not sure if it is working. I don't know how to test it. It is quite heavy. It weighs a little over 3 pounds. See photos for scale and size. Let me know if you have any questions. I am open to offers. I think there should be a key but I don't have it.
