Manufactured circa 1879-1886. Whitney produced only about 1,000 of these carbines in both small and large frame, with most of the production believed to have been sent to South and Central America. This particular carbine is a large frame variation, and features a blade front sight and folding ladder rear sight graduated to 900 yards. The top of the barrel ahead of the rear sight is marked with the two-line Whitney address, (reading from the right side), and "44 CAL" at the breech. The upper tang is marked with the two-line patent marking and the serial number is marked on the lower tang. Blue finish with casehardened hammer and lever, saddle ring and stud mounted on the upper left rear of the receiver, full magazine tube and mounted with a smooth forearm and straight grip stock with a crescent steel buttplate with compartment, (cleaning rod not included).
