I don't want to be a Debbie Downer but I attempted to have a nickel plated 32-20 re-nickeled. What I was not aware of was that if the original nickel is badly pitted, especially if the pits show any signs of rust extreme care must be exercised. The rustification will extend under the nickel and can look much worse than expected underneath the nickel. The revolver I had was in a similar condition as yours, excellent mechanics, pitted nickel finish. I talked with a refinisher who felt he could remove the nickel and possibly Cerracote or re blue depending on surface condition once nickel was removed. He had difficulty removing the nickel to his satisfaction, had the piece for six months or more and when finally finished I was very disappointed with the results. The poor old thing sits out in my shop in a case, just in case. I wasn't out a bunch of money on the original purchase and out of guilt the guy cut his fee radically.
