Friends, well I asked around with the local old timer diggers in the area of Wilmington and Fort Fisher. Nobody has dug a 12 lb WW shell, that they know of. A few bolts, but no shell or segmented shell.
As I said earlier a stacked pile of 6 lb'ers shells were found, and then a few 6 lb'er shells here and there north of the fort. None had fuzes, suspecting they had either a 'make-do' wood fuze, or they were fired in lieu of bolts.
There was one fella, who has since passed away, that was not into artillery that much, who once told me he dug a 12 lb WW with a fuze. His wife didn't like it in the house, so he threw it off the bridge !! Here's a mission for Diverdigger !! Unfortunately, with his passing so goes more info about the shell.......
Sorry I couldn't add more info to the conversation.......
