Jean-Louis Francois Devisme was among the most accomplished Parisian gunmakers in the 19th century, especially in the 1840s-1860s and counted King Louis-Philippe of France, Napoleon III, Queen Victoria of the United Kingdom, and other members of the British royal family among his clients. The rifled barrels have dovetailed bead front sights, silver bands at the muzzle and breech ends, silver dots along the side flats at the breech, silver scroll patterns, and "Devisme a Paris" in ornate silver script. Fixed notch rear sights are on the upper tangs. Aside from the barrels, the metal components feature relief engraved foliate scroll patterns that coordinate with the relief carved leaf and branch designs on the stocks. The patent breeches and standing breeches are marked "1" (A) and "2" (B), and the underside of the barrels and patent breeches are marked with "1" (B) and "2" (A) along with "LB" (Leopold Bernard), "11.0," Liege provisional proofs, and faint "crown/U" proofs. "JNI" is marked on the forends under the barrels. This marking has been noted on the carved ebony stocks of multiple pairs of pistols from the period. "10954" is marked on each stock at the toe. The case has an ornate lid escutcheon, "36 BOULEVART DES ITALIENS/DEVISME/ARQUEBUSIER BREVETE/A PARIS" in golden lettering inside the lid, and interior closely fit for the pistols and the included mallet, screwdriver, engraved ball mold numbered to the pair, nipple wrench, measure, two containers, a loading rod, and a cleaning rod.

Fine with aged patina on the silver inlays, mix of faded/cleaned period refinished blue and dark brown patina along the barrel, smooth French gray on the balance with darker backgrounds and a few spots of slight oxidation, and crisp engraving throughout. The stock is very fine and has crisp relief carving, some light scratches, light edge wear, and a few insignificant hairline cracks. Mechanically fine. The case and accessories are very good with minor age and storage related wear mainly concentrated on the case exterior, some light patina on the mold, and contact marks on the lining.
