In 1868, Remington began converting percussion revolvers for use with metallic cartridge skirting by the Rollin White patent issue through a partnership with Benjamin Kittredge who paid Smith & Wesson $1 for each converted revolver. Only 4,575 revolvers were converted ahead of the expiration of White's patent in April 1869. This revolver was originally manufactured under U.S. contract and has the White patent marking: "PATENTED APRIL 3d 1855" on the side of the cylinder. The barrel has the standard "pinched" blade front sight and markings on top. "142142" is on the bottom of the barrel, the left side of the grip frame, and inside the grips in pencil, and the trigger guard spur has the matching partial serial number "42/142." The grip frame also has"1" on both sides, "1582" and "24" on the left side, and "T", "V", and "649" on the right side. There are U.S. inspection marks, including a cartouche on the left grip.

Fine with 45% original blue finish remaining, smooth gray and brown patina on the balance, general mild overall wear, and some scratches and dings. The grips are also fine and have mild lower edge wear including small flakes and a chip on the upper right. Mechanically fine.
