Colt Model 1855 "First Model" Sporting Rifle & Carbine

This model was the first production longarm made at the Hartford factory. It was manufactured circa 1856 to 1859 with a total of approximately one thousand being made serial numbered from 1 to 1000. Most are in .36 caliber with a few manufactured in .40 caliber. It has a six shot cylinder and a round barrel which is semi-octagonal at the breech end. The standard carbine barrel length is 15 inches or 18 inches and the standard rifle barrel lengths are 21, 24, 27 and 30 inches.

The barrel address is ‘COLTS PT. / 1856 and ADDRESS COL. COLT/HARTFORD CT. U.S.A.’. The cylinder scene shows a hunter firing at five deer. The walnut stocks are varnished or oil finished with metal parts blued with case-colored hammer and lever.

This model is easily identified by the oiler device which is attached to the left side of the barrel lug, the absence of a forend, the unique cylinder roll scene and the spur- type trigger-guard.

On early low-numbered First Models the markings on the barrel are hand-engraved in old English and read ‘Address S. Colt Hartford Ct. U.S.A.’.
