I thought by the title you meant Cannon-ball, just hoped it was a whole one. Still OK though.
Get it. All a matter of perspective, I would prefer a whole one....For me this is as good or better than a whole cannonball. At this particular site I've found 6 cannonball of all calibers as well as many mortar fragments and even half a bar shot. This site was the scene of a prolonged engagement between the British and French in the early 1700s. I can just imagine this 8 pounder being fired and hitting something hard enough to fracture. Good times!
