Need help on this old Smith
Pick up this hand ejector it’s tight and the nickel finish is still fairly good grips appear to be original. It’s in 32 S&W Long. The serial number is 3168xx it’s has that same serial number in three places on the inside of the grip on the inside of the cylinder and on the barrel under the ejector. When you open the cylinder it has 25281 on the frame where the model number would be on the newer ones.On the bottom of the grip it’s stamped pat June 5th 1917 on the other side someone has put CPP on it, maybe their initials? On top of the barrel it has two lines that read smith and Wesson Springfield mass the second line has like three pat dates. How old is it and can I shoot modern Ammo in it?
