This isn't really artillery but it travels through the air and explodes so close enough. This is a 5-lber Ketchum grenade from Port Hudson that I picked up. They came in 1-lber, 3-lber and 5-lber sizes with the 3-lber being, I believe, the most common. Ronnie can confirm or correct that as I suspect he has seen thousands! The wooden shaft and fins are less than perfect reproductions. The iron is very good with a super grommet in the bottom for the plunger (missing). It was a size I've been looking for so very glad to get.
