Tour Stop 1 - 10-Pounder Parrot Rifle, (This cast iron rifle with its band of wrought iron reinforcing the breach was a modern weapon of the day, it was effective at moderately long range. The 20-pounder, similar except for size, was the heaviest rifled cannon used at Antietam) (narrative courtesy of plaque at gun)

Tour Stop 1 - 3-inch Ordnance Rifle, (This was one of the most accurate weapons used here. It was preferred over the much heavier 10-pounder parrot which fired the same size ammunition.) (Narrative courtesy of plaque at gun)
