My dad has a nice small gun collection, but at 80 years old he is now having trouble with his memory. He doesn't remember when or where he bought most of his guns and has stored all his paperwork in "a safe place" that we have not yet found. He has asked me to go through his collection with him to help identify what he has. His favorite is this Smith & Wesson 357 Magnum. I have a serial number, but can't find any model name or number on it. Can you guys give me any information on it or is there a website where I can use the serial number to get more information? Thanks.
