Description from text:

"Length 15 in., length of barrel 10 in., caliber about 7/16 of an inch. The wood is American black walnut. The barrel is octagonal, smooth bore. The lock is marked "Golcher." The barrel is marked " Patent No. 54." The barrel was originally finished brown, the other metal parts blue, and the wood either waxed or oiled. The barrel hooks to the breech is held by a key, and with the face-plate, which is brazed to it, is instantly removable. The four touch-holes are minute, to avoid loss of energy when the rear charges are fired. The three rear ones can be covered by hinged caps. The lock mechanism is boxed, and projects about 5/8 of an inch. The lock travels back and forth by hand between guides, and can be fixed in position at any touchhole by the same hinged caps that cover the holes. The trigger acts upon a long bar, raising it as one edge of a parallel ruler is raised, and the bar throws the sear of the lock wherever the lock is. There is a priming magazine, operated by the movement of the cock, which automatically flushes both the touchhole and the pan with pulverized powder. The general design is ingenious and simple."
