This used Prussian Model 1809 Potsdam is a .75 caliber percussion musket with a 41.25-inch round smoothbore barrel. The listing dates it to about the 1830s and records markings on the barrel and the lock plate. The lock holds at half and full cock with a strong spring.

The musket suits a collector of historic military long guns rather than a shooter looking for modern firepower. The barrel and metal parts are bright, with pin-prick surface oxidation and discoloration noted. The stock has a light varnish and a crack on the right side between the two barrel bands, and those are the details a owner should weigh. The listing dates the musket to about the 1830s, so its age is part of its description.
