I have been kicking around the idea of restoring my dad's old 1920's Harrington & Richardson breaktop .38 S&W revolver. It is in pretty bad shape with much of the nickle plating flaked off and some rust and pitting. The only mechanical thing wrong I can see is that the cylinder stop (if that's what it is called) appears to be broken because the cylinder will not lock unless you thumb back the hammer. I have watched a few YouTube videos and the disassembly, dremel cleaning and chemical stripping processes do not seem too bad but I am unsure of trying the copper and nickle plating myself. Has anyone with minimal gun repair experience tried a project like this and, if so, what advice can you give me. I love that is my dad's gun and he carried it in WWII but I can't afford to pay someone to restore it.
