This impressive revolving turret musket was manufactured c. late 1830s-1840s based on designs patented by John Webster Cochran (1811-1873) of New York City in the U.S. and manufactured by C.B. Allen and also patented through patent agent Moses Poole in the U.K. and manufactured by James Wilkinson & Son. This musket may have been built by the Wilkinson shop as a pattern/prototype piece for consideration by the military and is the only known of its type. It has a block front sight that would also serve as the bayonet stud, a long forearm, and heavy musket style stock with an iron buttplate. The only markings found are the Birmingham proof and "JW" (James Wilkinson presumably) markings on the left side of the barrel and number "27" on the action as well as the underside of the turret and upper stock mortise.
