Manufactured c. 1848-1850 based on the design of the trigger guard finial. Blade front and notch rear sights, with a pair of gold inlaid bands bordering the breech and "DERINGER/PHILADELa" on top, and a "P" on the upper left. Flourishes of floral scroll engraving are present on the German silver and iron, including the lockplate which is also marked "DERINGER/PHILADEL". There is a blank German silver escutcheon on the wrist and a small cap compartment in the butt.

Fine, retains 70% of the original brown finish with striped patterns and strong traces of the mostly muted original case colors in sheltered areas with the balance having thinned to a smooth grey patina. The trigger guard and wrist escutcheon retain most of the original silver plating. The stock is also fine with a minor chip absent near the upper tang, some light handling marks, and crisp checkering. Mechanically functions fine except is missing the safety notch in the hammer.
