Ever heard of a cannononball .. ovoid?

[fernando]

This item lacks the basic condition for a ball, as it is not round ... but ovoid.
However the (non professional) seller guaranteed this is surely a cannonball, kept by the family for a long time and having been found in a place where actually plenty war confrontations took place, both internal and Napoleonic.
The weight and average diameter coincide with an 18 pounder.
Byt i don't think this thing could be fired as it is; neither its deformation could be achieved by rolling on the ground after being shot ... it wouldn't become so perfectly ovoid.
On the other hand, its texture looks exactky like that of a 18th or 19th century cannonball.
What do you gentlemen think of this?
Ever seen one like that?
