This is a rare high condition low serial number 46 1861 Navy. Only a couple of thousand of these were converted to metallic cartridge. Cal 38 RF. High condition gun with nice smooth metal. All addresses are very readable and even a full cylinder scene remains. Color is mostly a pleasing antique grey with some blue in protected areas. Remnants of case colors on the frame. Nice aged looking brass and good grips. A very good collectible piece!
