Manufactured by the Schlotterbeck Brothers. Brass blade front and notch rear sights, J. Deringer address on the breech and lock, and "WART/STEEL" on the upper right barrel side. The striped gray and brown finish on the barrel in emulation of Deringer's "bronzing" process is rarely seen on imitators and, in this case, is expertly applied. Scrollwork and zig-zag borders on several components, floral blossom pattern on the escutcheons, and burst patterns on the bolster. The guard and shield have an unengraved stripe running from upper right to lower left, and the former is marked "14" below the rear screw, which is repeated on the inside surface of the hammer. Fancy checkered bird's head stock with smooth triangular tip insert running nearly to the finial.

Andrew Wurfflein operated in and around Philadelphia from 1845-1871. Dovetailed German silver blade front and notch rear sights, "A. WURFFLEIN/PHILa" on the top flat, "STEEL" on the upper right, and gold bands at the breech. Scroll engraving on several components, burst pattern on the reverse plate screw, pineapple finial, and checkered bird's head grip.
