From what I have learned about this device, it would have been mounted in the cockpit of a Navy plane equipped to drop torpedoes. The torpedo director then essentially steers the torpedo into the target. This unit is in excellent condition and is complete with the acrylic cover and all original labels and decals. It was manufactured by Bay Electric Auto-Lite and was used with the MK-13 torpedo. A truly stunning piece of World War II memorabilia.
