1961 Mattel Sonar Sub Hunt vintage game. This game does work. Both the buzzer and the light are functional. The "READY" button is missing. You can push the center part down with a pen or a screwdriver instead of the "READY" button when firing and see the light come on to indicate a hit. The game is incomplete. There are 3 green and 3 grey submarines. There are 3 mines. The mines have broken pins. The box is in fair condition with some separations in the top. Requires 1 D size battery. I can also provide a photocopy of the game instructions.
