This is a very nice Henry Deringer 41 caliber percussion pistol. It is marked N. Curry & Br. San Francisco Cal Agents. This has a 1 ¾” barrel and is finished with nickel silver trim. N. Curry & Bro. San Francisco Cal about 1863. The mechanical function is very good crisp and tight and a nice bore. There are two platinum inlays and a silver escutcheon plate behind the tang. There is one tiny grain crack near the escutcheon screw on the left side. Otherwise this is a very nice San Francisco Agent marked Henry Deringer.
