Whitney Pocket, .31 cal. percussion single action revolver. Serial # 4 - - - , mfg. 1860's. Good condition. One the small frame the pocket configuration is apt. 6" octagon barrel is dark. Mechanism works OK, but the hammer spring is very strong. Appears to be a gun that was buffed and then reblued long ago as only one digit appears on the serial number and a partial faint "E. Whitney" is on the barrel flat top. Brass triggerguard. Some fading blue. No engraving on the non-fluted cylinder. Smooth walnut grips have shrinkage. Nice representative sample that a Civil War officer might have carried behind the lines. Antique. Can ship to your doorstep. Gunrunner West item.
