Reportedly, only 770 Merrill rifles were manufactured by James H. Merrill for the U.S. Ordnance Department between 1862-1865. These rifles are generally considered to be among the rarest and most sought-after percussion rifles of the war. These rifles were also issued in limited numbers to sharpshooters in Michigan, Arkansas, and Massachusetts regiments. The 21st Indiana Volunteer Infantry (1st Indiana Heavy Artillery) Regiment are the only known regiment to be armed almost entirely with these rifles. This example is inscribed "William Lutzman" in fancy script on the underside of the brass trigger guard, who has been found to very likely be William L. Lutzman, a Union soldier with Company K of the 1st Indiana Heavy Artillery! The 1st Indiana Heavy Artillery Regiment was involved in numerous battles throughout the Civil War between 1862-1865 including the Battle of Baton Rouge, Bayou Teche Campaign, Siege of Port Hudson, Battle of Mobile Bay, Battle of Spanish Fort, and the Battle of Fort Blakely. It should be noted that this rare example is fitted with iron barrel bands and an iron patchbox; unlike the majority of these Merrill rifles that are brass mounted. Matching serial number "1469" marked on the top rear of the breech lever and on the tail of the lock. Modern replacement flip-up two leaf rear sight. "GDM" (George D. Moller) collection initials marked at the toe of the stock. Includes a reproduction leather sling. Provenance: The George Moller Collection
