Reading a gun's marks

A Civil War cannon commonly carries a set of markings on its muzzle face, trunnions, and breech: the foundry that cast it, its weight, a registry or serial number, the year, and the initials of the inspector who accepted it. Together these tell much of the gun's history.

Comparing a gun's marks against known foundry practices and inspector records is central to identifying and dating surviving cannon.
