Description:

U.S. NAVY COMPUTING GUN SIGHT
U.S. Navy Mark 18 Mod. 1 gyroscopically-computing gun sight, approx. 7 1/2" x 5" x 6 1/2", commonly used in most naval fighter aircraft during World War II. The top of the casing bears a metal plaque giving the model name and identifying the manufacturer as the Lukas-Harold Corp. of Indianapolis. The sight functions by projecting two illuminated reticules onto an angled piece of glass; the reticules are gyroscopically calibrated based on the wingspan of the enemy aircraft, as set by a dial facing the pilot. The sight hood is fitted with a hinged polarizing filter, allowing for greater visibility in high-glare conditions; the hood is also stenciled "No Hand Hold". The metal-sheathed power cable in present and intact, very good overall.
