Its a k frame .357 mag. Serial num is on the but like all others and also on the chamber side of the cylinder along with the k stamped there also. Where the model is on my others there are some numbers I can't figure out what they are.
A few years back my dad gave me a .38 S&W that my aunt had thrown in the trash. She asked him if he would take out the trash & there it was. Nickel plated with real ivory grips. I'm not sure of the model as it's not on it. It's so old the ivory has turned yellow & shrunk. Has a little pitting on it decent shooter. It's my pimp gun.
