The Butterfield Revolvers were manufactured by Jesse Butterfield of Philadelphia, Pennsylvania, in 1862. They are considered by collectors to be secondary U.S. martial handguns since they were manufactured in anticipation of an unrealized government contract. Because no contract was awarded, production was limited to only about 640 revolvers. It is equipped with a special disc priming device loaded by loosening a thumb-screw in front of the trigger guard. The top strap is marked "BUTTERFIELD'S/PATENT DEC.11 1855/PHILADA". The butt is numbered "462," but the remaining components have "442." This may be a mix-up at the factory.

Good with mostly a natural aged patina on the frame, dark patina and extensive mild pitting on the barrel and cylinder, and even overall wear. The right grip is cracked where it screws to the side plate (not visible without disassembly), but the refinished grips are otherwise good with moderate handling marks. Mechanically fine.
