I just purchased a Stella 17.5-inch disc music box with lead corrosion
that's going to need some repairs. My question is: can it be repaired
if all the lead weights are completely corroded and crumbling?

If so, what restorer would you recommend and what approximately will
it cost? Is there a publication that shows how to do it?

Thanks very much.
