S&S Sporting @ 208-313-1570. They take their time when polishing, much of which is done by hand on revolvers like yours and will not polish any markings or proof marks off the revolver or round off corners. I've seen some realy scary refinishes that really make you mad. This guy is good, loves firearms and would not dare mess up a beautiful weapon such as you have. His prices are very reasonable and turn around time is pretty quick. He blues at least a couple times a week
