These tiniest of percussion derringers are very popular with collectors. This one was manufactured around the 1860s, likely by Slotter & Co. The barrel has seven-groove rifling, a German silver blade front sight, notch rear sight on the tang, "N. CURRY & BRO./SAN FRANCO CALA/AGENTS" marked on top, and "DERINGER/PHILADA" and "P" marked on the German silver banded breech plug. The lock is marked "DERINGER/PHILADELA." There is some floral and scroll engraving. "8" is marked on the trigger guard tang, wedge, and likely on the inside of the lock and bottom of the barrel.

Very good with traces of original brown and casehardened finish mixed with dark patina, repaired hammer, and generally fairly minor wear. The refinished stock is also very good and has crisp checkering, and minor dings. Mechanically fine.
