I have a wooden artillery shell that was made around WWII, to train crews on loading & firing. Some guy had the idea to make those, so they could save the real shells for the battlefield. The army ordered them, but I don't know if they ever had to use them. It's a pretty cool "conversation starter" now.

My late Dad’s National Guard armory had a pair of those on display that they prized more than the real thing. When I was very young I got to polish them. ;-)
