This is an early example of an exploding fort. The box does not have a model number and neither does the printing plate. The fort measures 12″ x 6″ and the tank is 6.5″ x 1.75″. There is a mouse trap spring under the red deck of the fort. When the red target on the front of the fort is struck by the projectile from the tank the floor of the fort and everything on it explodes into the air.
