So I have had a Smith &Wesson handed down to me by my grandfather for several years now. There is a high end ( at least to me) gun shop in the next town. They had a gun similar to mine for $1200. I understand condition age how many were made ect all play into pricing. Well to me the coolest thing about my gun is the original box and receipt where I guess my great uncle paid $63 and change for it in 1953. I was showing it off today to a customer. Who owns a gun store he offered me $400. So it got me thinking and that led me here. According to the box it's a S&W mp with two inch barrel fixed rear sight. The bottom of the butt has C 161. I already put it back in the safe so I will get the other numbers tomorrow. Looking more to age the gun but value not a bad thing to know. Thank you and I have enjoyed reading a few of the threads
