Model and Age of S&W .357
I am attempting to determine the model number of my dad's old duty weapon he carried for many years as a police officer.
There is no model number in the normal location, like my other S&W revolvers.
It is a large frame. The serial number has a "C" stamped above it. The serial number is "189xx". In the ejector relief of the frame it is stamped "7s151"
Could anyone help me determine the model and age of this revolver?
