The serial number is 677. It can be seen on the butt of the gun in one of the pictures. Lots of differing opinions. In my opinion what you've all helped me identify is a Model of 1899 K-frame that fires .32/20 Winchester cartridges. I'm assuming that with a serial number of 677 it was probably built in 1899. Please correct me if I am wrong. Can't thank you enough for the help.
