Use fine steel wool and/or a flat metal screwdriver tip or something similar that will not scratch the finish but will scrape off the rust. The bolt parts should be easily located but the stock itself will be more difficult and you could wind up getting more into it than it's worth. The mum and matching numbers would make it worth my time to put it back together if I could get the parts reasonably.
