My father passed away in 1989 when I was nine years old. I have been left a extensive collection of firearms. I am very proud of my collection, but I have three pistols that I need some id help with. This picture is a model 657 .41 mag three inch barrel. serial #ane3xxx. I also have a 624 44 special, and a 686 .357 all three are in the same figuration as this 657, 3 inch finger groverips adjustable sights. I have the boxes for these so I know they are original guns from s & w. My question is they dont list 3 inch guns in any of the listings in blue book. Any smith guys out there can give me som info? the 657 has had the trigger and hammer jeweled, the rest are stock. Thanks richard.
