Pennsylvania Airgun show

I don't know why I never got around to verifying it's location. I live 5 minutes from that war college. I'm not a vet but know a hundred folks who are and live close to me.

I think I heard on the net somewhere that a gun "believed" to be the one from Lewis and clark was in the army museum in Virginia. It seems nobody is sure what happened to their actual airgun. The world only has a few survivors. There are reproductions and repo parts.
