Previous manufacturer located in New Haven, CT, 1798-1886.
Whitney Arms Company began firearms production in 1798. Eli Whitney Sr. & Eli Whitney Jr. were prominent figures and prolific producers in the arms manufacturing world for a great many years, and their production plant in New Haven is credited as being the first major manufacturer of commercial firearms in America. The Whitneys produced a tremendous variety of firearms under family ownership for approximately 90 years before selling the company to Winchester in 1888. Numerous long arms, starting with the Whitney 1798 U.S. Contract Musket, and moving forward through various other flintlock, percussion, rimfire, and centerfire rifles, handguns, and shotguns, contributed to the vast broadness of the Whitney line. Whitney collaborated with Burgess, Kennedy, Morse, Tiesing, Howard, Cochran, Scharf, and many others. Many of the early Whitney rifles, such as the historic 1798 Flintlock muskets, are rare and highly collectible, commanding substantial premiums when found in original configuration, and not converted to percussion. The Whitney lever action repeaters are also quite popular among collectors. A fair number remain in circulation.
