I just received a S&W 357 Magnum from my step father and as near as I can tell it is a non registered pre war 357. I have been searching the web for any information that I can find and was hoping someone here could direct me to a good source for information (books or websites). This is my first Smith so I know nothing about them, this particular revolver has a 8 3/8 inch barrel and the serial number is 62XXX. I am courious about the age and quantity of them made with 8 3/8 inch barrels.

Thank You,
Shawn
