Spent time fishing and exploring Hatteras last week. The Graveyard of the Atlantic Museum has some fascinating muzzleloading weapons. I took the best pictures I could. The mini cannon is a Lyle Gun, mostly used for firing lifesaving floats out to shipwreck victims. The torpedo looking projectile above it is one example. I think Lyle Guns were also used in a few defensive situations. Other guns are military issue and nice custom percussion rifles and pistols, used in the Civil War.
