The cannon has a cast-iron tube 24 inches long, with bore approximately 1-5/8 inches. There is a heavy cascabel at the breech and a pronounced muzzle swell of short-radius semicircular profile. The trunnions, which are cast integral with the tube, are on the center line, and there is a cast pan for a priming charge and a rudimentary ring-shaped reinforce. The tube is mounted in a small wooden field carriage, 26 1/2 inches long, with wooden wheels 15 3/4 inches in diameter. Hubs, spokes and felloes are all wood; there are thin iron reinforcing bands on both sides of each hub, and thin iron tires that have been forge welded into a continuous circle. One cheek of the carriage has been broken long ago and reinforced with an iron strap bolted on. The tube is a sand casting, showing a definite mold separation line parallel with the bore, running forward from the flash pan. The interior, now eroded, shows no evidence of having been bored after casting.
