Colt Model 1851 Navy, .36 cal. percussion single action revolver. Serial #136491, mfg. 1863. Fair condition. Interesting Navy that appears to have a unit number on its right grip panel (see photo) indicating service in the Civil War. Octagon barrel has been shortened nicely to 6 1/4". Dark bore. Gray gun with shined up brass triggerguard and grip frame. Matching serial numbers. Some of the nipples are beat down and one is missing. Indexes OK. Readable barrel address and "Colt Pat." on left side of frame. Walnut grips have shrink some and/or been sanded on the bottoms. Potential here for the ultimte display piece of the Civil War! Antique.
