Can you post a picture or two of the bell, please. You have already identified what you have and the provenance, so there's not much to add to that. I can, however, advise you on conservation/restoration and whether or not to do that and how to go about it once I see the condition.
I'll be happy to give you further information on your object once I'm able to see images of it.
Please contact the Just Answer site help desk for assistance with payments. As an expert, I do not get paid unless I am rated for my work. I am willing to assist you with your restoration/conservation question upon receiving more information.
