I was born in 1972 and would like to find a S&W revolver that was introduced in 1972. Or at the least, changed in 1972, by becoming a dash something. I'd prefer stainless and .357 (or larger) and once I find the model number that I am looking for, I will be looking for complete w/ box and documents. But, the hunt starts w/ the model. I have done limited research and haven't come up w/ much and know a few of you will have the information on the top of your head.
