Picked this one up at gun show in Medford, Or. two weeks ago. .38 spl., 4 inch, no special markings, sn: 4446xx. Shoots to point of aim, just have to figure out to hold sights. What is the year of maufacture or shipping? The side plate seems to be a tad pitted and the finish looks different than the rest of the revolver. Are the side plates easy to replace if I choose to do so. This one will be my pickup revolver on the ranch, so I guess the finish is not that important.
