I'm trying to find out what I have ? It has a one & seven eights in. pinned barrel with 9818 E? on the bottom. On the frame with the cylinder open the letter M 43948 & on the yoke its self 43948. On the butt 9818 & on the cylinder above the extractor 9818. On the frame under the right grip the letters M H. It is a five srew with a flat cylinder latch,round butt, walnut diamond grips. Mechanical is near new with 90% of its blue, NO rust. If one of you guys can tell me when it was made & what it is worth I sure would appreciate it. ONE more thing, the ampersand ( & ) in S&W is differant. Thanks ahead Tom Reynolds Wanna kill these ads? We can help!
