This is an example of a Roper Revolving shotgun that was produced at Amherst, Massachusetts, from 1867 to 1868 by the Roper Repeating Rifle Company. This shotgun is stamped "ROPER REPEATING RIFLE CO./AMHERST. MASS./PATENTED. APRIL 10, 1866" on the hinged dust cover over the revolving mechanism. The serial number is marked on the barrel and on the frame under the forearm. Equipped with the Roper patent removable choke ring at the muzzle. This shotgun used special steel cartridges. The four shot carriers (consisting of a series of fins) are enclosed within a large round housing with a hinged loading gate on top. The hammer pulled the sliding breechblock to the rear, removing the fired case from the barrel, then revolving the cloverleaf carrier, and when the trigger was pulled, pushing the next cartridge into the barrel and fired it. The barrel is blued, frame, while the trigger guard, and housing are casehardened, and the forearm end is pewter. Smooth forearm and straight grip stock with a steel shotgun butt.

Fine. The barrel retains 50% of the original blue with the balance of a smooth blue/brown patina while the remaining metal parts have a smooth mottled grey patina. The wood is very good with horizontal cracks visible in the wrist, scattered minor dents, and scratches. The markings are crisp. Mechanically fine.
