This is a scarce London Armoury Co. Kerr's Patent percussion revolver with Confederate "J.S/anchor" markings on the grip between the lower tang and grip cap. The anchor stamp is believed to have been applied as an export stamp for revolvers purchased by the Confederate government. The right side of the frame is marked "KERR'S PATENT. 9655.", and the left side is marked "LONDON/ARMOURY". "LONDON ARMOURY CO." on the lock plate. The upper left barrel flat is stamped "L.A.C." followed by two British proofmarks. The cylinder is also marked with proofs between the chambers and the matching serial number. The cylinder has the serial number engraved on it. Kerr revolvers use the same style lock mechanism as was employed in rifles and muskets at the time allowing for easier battlefield maintenance and saw wide use among Confederate forces. At least one pair are known to have been owned by Jefferson Davis and presented to Given Campbell during his failed retreat from Richmond at the end of the war.
