Vintage Antique Chinese Export Brass Enamel Charm Bracelet needs Repair For Sale

This charm bracelet is an antique survivor. It is missing a charm ( I think it was possibly a fish). There is verdigris forming on the brass, and one of the connecting jump rings has been replaced.
My mother's grandfather was a sea captain, and this was in her mother's things. We think it may have been brought back as a gift for her (from father to daughter). The clasp works great. Please see all photos and video for a complete description.
