We should be able to repair the piece in some fashion. As far as a replacement; online or antique stores. Even if you find replacement chances are it will need to be altered to fit your base. They usually are not interchangeable. Best to bring in the pieces and we can see what we can do. We have worked on many epergnes over the years.
If you saved the pieces, chances are good that Rattay’s can repair it like new.
