With only three believed to exist, the ivory stock Deringer is the paramount in the Deringer collecting field. The stock on this pistol has a grip area that is sharply checkered and features a double line border. A silver shield escutcheon inset is behind the barrel tang and is decorated along the top with a matte pattern and straight lines down the sides ending in a floral bloom pattern. A triangular plate is set into the tip of the stock with matte border work. The butt is fitted with a matte bordered and line accented buttplate with a trapdoor cap compartment. The trigger guard finial is pineapple shaped which indicates production in the early 1850s. The lock plate and the breech plug are both marked "DERINGER/PHILADELA". The letter "P" is stamped next to scrollwork on the left barrel flat. The long style breech plug features a pair of 12k gold bands and the coin silver furniture is extensively engraved. The lock plate, hammer and trigger guard are nicely broad leaf floral scroll engraved. The tang of the breech plug tapers down to a rounded point on the rear and is fully engraved. Matte and zig-zag engraving patterns are visible on some parts, including the trigger guard, reverse plate, hammer and accent plate. The barrel is fitted with a dove tailed German silver blade front sight and there is a notch rear sight on the barrel tang.
