Nemours is one of the many DuPont family properties in the Phila-Wilmington area. There are two cannons at the "love temple" at Nemours which are said to have served in USS CONSTITUTION. I've only found one not-very-useful photo of one from the muzzle end, can't tell much at all.
Does anyone have good photos of these guns, other info? Anyone curious enough to call the place to get photos/info? Anyone close enough to to go in and take photos, measurements, etc (I'd pay your admission.)
I'm a member of the Naval Historical Foundation, which asked if I could find out anything ahout those cannon, but I don't have time to chase it down myself.
