This old gun has been laying around on my shelf for about 20 years and I never have gotten a fix on its age or value (lack of?). It was nickel plated at one time, but that's almost all gone and the cylinder is rough with rust on the outside. It has a low 4-digit serial number (8xxx) on the bottom of the trigger guard. It has black hard rubber grips with the owl head facing the butt. Does anyone know roughly how old this gun is, and can anyone explain the significance of the orientation of the owl head?
