This c. 1830s-1840s rifle is marked "S. MORRISON [star] MILTON [star] PA" on top of the barrel and has traditional blade and notch sights and some wavy entwining line patterns flanking the rear sight. The lock has an external mainspring and sear. It is fired using adjustable double set triggers. The curly maple stock has sixteen silver inlays along with brass furniture, including a wear plate on the forend, comb plate, toe plate, and four-piece patchbox with pierced side plates and finial. Both the silver inlays and some of the furniture have wavy line borders. Samuel Morrison (d. 1844) of Milton, Pennsylvania, was active in the early 19th century. One of his sons, also named Samuel (d. 1850), was also a gunmaker in Milton before he opened a shop in Pekin, Illinois, and this rifle may be his work. Many of the surviving Samuel Morrison rifles from Milton are "side slappers" using a variety of lock designs.

Very good with dark brown patina on the lock and barrel, mild oxidation and pitting mainly at the breech, attractively aged patinas on the silver and brass, and generally mild overall wear. The stock is fine and has attractive figure, mild scratches and dings, and a few cracks and repairs, including a crack through the toe section. The lock appears to have been modified with a replaced spring and requires some assistance to function.
