Overall length 54.75"; barrel (bore) length 35"; caliber .577. Markings on breechblock-bolt mechanism: "BROWN MFG. CO. NEWBURYPORT, MASS./PATANTED OCT. 17, 1871". Patent issued to George Merrill in 1871, permitted Brown Manufacturing Co. to alter probably up to 1,000 English P1853 rifle-muskets to single-shot breechloading system. Large bolt handle projecting upward at end of breech readily distinguishes these arms.
