A friend in Ok. has a canon ball that was dug at Pea Ridge 80 years ago. It is a round ball and he said it had what he thought was a plug in it. On the plug is the letter "A". He said when you shake it that there is something inside. I told him not to shake it that it may be live. He said it weight was about 6 lbs. Do you know what the A stands for on the plug? Where would he find somebody to tell him if it is safe or not? Any help will be appreciated.
