This is an exceptional, totally original example of a British proofed Colt Model 1855 Revolving Carbine that was manufactured circa 1862. Colt Model 1855 Revolving Carbines are a rare variation of the Colt Model 1855 Revolving Rifle. Colt London Agency sold approximately 2,000 Model 1855 Revolving Carbines.

Excellent plus. The carbine shows very little wear and retains 97% of the original blue and casehardened finish. The military blue finish has traces of plum brown patina on contact points of the barrel, cylinder and frame. The percussion nipples and rear face of the cylinder show minute evidence of having been fired. The hammer, face of the cylinder, breech and inside of the frame show no sign of ever being fired. The loading lever and hammer retain 98% plus of the original casehardened finish. The screw-heads are in perfect condition and retain most of the niter blue finish. The brass trigger guard and buttplate have a pristine "mustard yellow" age patina. The proof marks, serial numbers and Colt markings on the cylinder and the top of the frame are crisp. The stock is in nearly new condition with all of the original oil finish. The stock shows almost no handling or storage wear and retains the un-touched, "feathered" grain. This is certainly one of the finest examples of the rare Colt Model 1855 Revolving Carbine extant. It is most likely the finest example of a Colt Model 1855 Revolving Carbine ever offered for sale by the Rock Island Auction Co.
