I stopped myself from posting a dozen times because I do not want to sound offensive to the OP. On the contrary, a revolver that carries this kind of personal significance carries far more value than its worth in currency. I could certainly be wrong (I usually am) but I get the sense that the OP does not have the skills or tools to repair this revolver (right now). This is not a knock, but an observation and opinion. I apologize if it is not taken as the constructive criticism it is meant to be. I think it's an excellent choice to not treat it as a DIY project at this point. This is certainly the best place to come for the information you seek even if some old opinionated guy like me has to throw in his 2 cents. Best of luck with your endeavor.
