I was given an Iver Johnson Top break Revolver that appears to be in .32, small frame. Very tough shape. My friend knows I like to research stuff and track down parts, so he gave me this little puzzle. 5 shot, Coil spring, Matching serial numbers on Grip, trigger-guard, and barrel-shroud. Owls have been worn/sanded off. On the left grip frame the serial number is A 3034, the other two locations only have 3034. I am trying to find a detailed parts list or exploded diagram, disassembly advice and a source for some parts. Not trying to restore it, and I know there isn't much value. Just trying to do the genealogy.
