In 1848, Colt acquired a number of Model 1839 Carbines (approximately 40) from the state of Rhode Island. In an effort to make them marketable they were refinished and the majority fitted with plain cylinders (brightly polished) having integral ratchets around the arbor hole. Barrel length 24"; caliber .525; barrel browned; cylinder polished; frame blued; furniture case-hardened; walnut stock varnished.
