This game was produced by Toy Creations during the war. The only metal in it are the needles on the bombs. The sight has a mirror in it and works like a periscope. You would hold the sight over the board and aim at the target. When you thought you were lined up with the target a red lever is pulled and a bomb is dropped. The bomb has a sharp needle like point that will stick into just about anything.
