The Heavy Holy Grail of Colt Revolvers- The rare Colt Walker Model 1847 is a 6-shot, single-action revolver weighing in at 4-1/2 lb & measuring a 1-1/2' in length. It was the weighty brainchild of Samuel Colt & Samuel Walker. Walker met with Colt in the 1840s to propose improvements to the Colt Paterson revolver...the result was the Colt Walker. Fewer than 10% of the 1,100 are known to exist today. Due to their rarity, these guns are the Holy Grail of Colt revolver collecting. NRA Museums.
COLT M1861 NAVY REVOLVER: On the underside of the barrel are U.S. Navy inspector markings. Similar to the Richards-Mason alteration done after the Civil War for M1860 percussion revolvers, only about 2,200 of these M1861 Navy conversions were done at Colt's Hartford factory.
