Picked up my first Model 65 today; 4 inch, square butt, P&R, grips are serialed to the gun. It's marked "C.P.D." on the left side under the cylinder. I've only found one other reference to a gun marked this way that indicates it was a Cincinnati Police gun. I think it's a 1979ish vintage based on the serial # 1D79XXX. The gun definitley was a duty weapon for a right handed officer. Gun was very dirty, but cleaned up nicely. Anyone else have a police marked revolver? Was it marked by the factory or after by the agency?
