Commonly called "Potsdam" muskets after the Potsdam Arsenal where many of these muskets originated. These muskets and rifled-muskets were imported in large numbers during the American Civil War. This example was manufactured c. 1833 and later converted to percussion, rifled, and fitted with long range sights. Features blade, notch, and folding ladder sights, "crown/FW/Saarn" on the lock, "705" on top of the barrel, "462" on the left barrel flat and left stock flat, various Prussian proof and inspection marks, and "110313/40 084/1833" on the buttplate.

Features blade and notch sights, an unclear maker mark under the "crown/FW" mark on the lock (appears to start with "Lug"), Prussian markings on the left stock flat, and "33550" on the buttplate.
