I doubt there is anything one can do with the Old Army to make it resemble a real C&B revolver. It's just a modern revolver built to be loaded the old fashioned way, whether with fixed or adjustable sights. You have to appreciate the Ruger for what it is, a big, heavy, rugged, reliable and accurate revolver built to last several lifetimes. But there is nothing you can do to it that will make it look natural with a buckskin shirt.
