"MASS" marked on top of the breech and stamped in the left stock flat. "W.GREENER,1861." marked on top of the barrel behind the rear sight. A crown is marked at the tail of the lock and "GREENER" at the center. London crown proofs and "25" gauge markings on the left of the breech indicating .577 caliber. Includes a socket bayonet marked "C/D.I/132" on the collar.

Very good, the barrel has been polished bright, with smooth dark brown patina on the barrel bands, rear sight, lock and hammer, and darkened aged patina on the brass trigger guard and buttplate. Stock is very fine with some light scratches and dents, a crack behind the lock, and distinct edges overall. Mechanically excellent. Included bayonet is very good.
