Engraved Remington O/U Derringer, SN 165, early two-line barrel address, beautiful scroll engraving probably done by Nimschke, overall gun displays a fair amount of usage but metal is smooth and clean. 50% original nickel remains on barrels, balance of exposed metal is a dark patina. Considerable gold wash is intact under the beautifully aged pearl grips, solid hinges, mechanics excellent. Rare, highly engraved example.
