This 19th century American combination gun is marked "P. KOCKLER/LEWISBURG" on the upper barrel which is .44 caliber and rifled and has a dovetailed German silver blade front sight and dovetailed iron notch rear sight. The lower barrel is .43 caliber and smoothbore. A shared ramrod is fitted to the right. The locks have scroll engraving. The mounts are German silver and include a stag inlay on the cheekpiece. The stock is curly maple with a raised shell carved forend tip. A detailed write-up on Kockler accompanies the rifle and notes that Philip Kockler (1828-1888) was born in Prussia and immigrated to the United States in the 1830s with his parents and lived and worked in Lewisburg, Union County, Pennsylvania, c. 1862-1888 after apprenticing under Frederick Beerstecher who worked in Philadelphia in 1846-1857 and then Lewisburg c. 1857-1868 before moving on to Michigan. The consignor estimated this rifle was manufactured around 1870.

Good with much of the refinished blue finish remaining over moderate pitting, light aged patina on the German silver mounts, and mild overall wear. The refinished stock has repairs including screw affixed brass plates repairing a crack on the underside at the breech, cracks, mild wear, and attractive flame figure. The triggers and locks need work.
