This gun is pictured and listed as a "Boy's model" from the Ronald G. Gabel Collection in "The Wurffleins of Philadelphia: Artisans at the End of an Era" by Ronelle Willadsen. This rifle was manufactured by John Wurfflein Jr. and Frederick Psotta during their brief partnership. Though their partnership is often listed as starting around 1851 by more recent authors, Wurfflein & Psotta were already running newspaper advertisements for the shop at 98 South 3rd Street in Philadelphia at least as early as June 1850, and there are other documented references to the partnership from the same year. The rifle has a German silver blade front sight, adjustable sporting rear sight, "J. WURFFLEIN & PSOTTA PHILADA" on top of the barrel, gold and German silver bands at the breech, scrollwork engraving on the lock and other components, German silver wedge plates and nose cap, double set triggers, a silver shell pattern cap box, and a nicely figured stock with checkered wrist, right side cheek rest with relief carved scrollwork at the tail, and an accent line extending around the left side.
