I have an old S&W 32 Long CTG. It's got some surface rust on the actual frame and needs a firing pin. the cylinder on this revolver spins nice, quite and smooth. There are patent dates on the top side of the barrel. The last one is Dec 29, 14. I'm assuming that's from 1914 but I know they made these well past WW2. All the research I can find online really does give too much information let alone where to find the pin that goes from the hammer to the actual cylinder being fired. If anyone has any kind of information or can point me in the right direction I would be greatly appreciated!!!! Thanks in advance and I will probably thank you again!!!
