Original Gettysburg battlefield recovered medium size cannon (canister ball) found on East Cemetery Hill. We have a very limited amount of these. Each will vary from the one in the 1st photo. We will pick the best one from our current inventory. Canister was shot from cannons. Many balls were packed into a can and when fired it went out of the cannon barrel like a giant shotgun. Museum documentation (COA) provided. Larger canister like this from Gettysburg is very scarce.
