Manufactured c. 1860s by George O. Leonard at his shop in Keene, New Hampshire. It features a blade front and adjustable notch rear sights on the .38 caliber rifled upper barrel which is marked "GEO. O. LEONARD KEENE N.H." The lower barrel is approximately 12 gauge smoothbore. The upper tang has a tap for a now absent peep sight. A ramrod for the shotgun barrel is fitted along the right side, and a smaller rod for the rifled barrel is along the left. The locks are marked "Wm READ & SON./BOSTON" and have scroll and border engraving. The left lock has an extension added to the hammer to reach the nipple for the shotgun barrel. The furniture is brass. The stock has a cheekrest on the left and a capbox with a stag finial on the right.

Very good with mix of fading original brown finish and brown patina on the barrels, mostly gray-brown patina on the locks, some mild pitting on the hammers and breech ends, attractive aged patina on the furniture, and mild overall wear. The stock is also fine and has most of the finish remaining, some dings and scratches, and mild edge wear. Mechanically fine.
