I got my first S&W revolver & interested in finding out a bit about it. I bought it from a friend that was in serious need of cash. I didn't haggle, low ball or any of that; he set the price & I paid it. Now I'm looking to find out what I can about it. I have no knowledge about Smith's, but from my last hour of internet searching I believe I have a N frame. Not even sure what that means.... It's a .357 magnum with a 4" barrel. It needs some attention cosmetically (blueing) , has a bit of rust build up on the rear sight, & the lettering on the barrel is about rubbed off due to holster drawing (me thinks). I didn't get a box or paperwork (factory supplied), as a matter of fact I got another gun in the deal he found that he didn't know he had until after the first conversation about wanting to sell this one. I will try to attach a pic. I did date it by serial # to 1954 or 1955. I hope to learn a lot here & look forward to passing what knowledge I do have on.
