Manufactured around the 1860s, likely by Slotter & Co. The barrel is marked "N. CURRY & BRO./SAN FRANCO CALA/AGENTS" (factory/retailer error/double stamped), and a "P" is on the German silver banded breech plug. The lock is marked "DERINGER/PHILADELA." Most of the components have "IV" assembly marks.

Good with dark gray and brown patina, light oxidation, some small nicks and scratches, and aged patina on the German silver. The stock is also good with mostly crisp checkering, extensively flaked varnish, and mild handling wear. Mechanically fine.
