In 1863, Nathaniel and John Curry inherited their brother Charles's business and operated as wholesalers and sales agents for Henry Deringer's popular pocket pistols and rifles. They also sold the forgeries made by Slotter & Co. and remained active dealers through the "Silver Age" until 1886 when they sold the firm to Charles Ladd. The barrel has seven-groove rifling and a faux Damascus finish and is marked "N. CURRY & BRO./SAN FRANCO CALA/AGENTS," and a "P" and "DERINGER/PHILADELA" is on the German silver banded breech plug. The lock is also marked "DERINGER/PHILADELA." The breech plug, lock, and German silver furniture have primarily scroll engraving, and the butt also has a small cap compartment. "6" is marked on the trigger guard tang, wedge, barrel, breechplug, and cap compartment lid.
