Scale: 1/200

Set includes 4 turrets (2 with rangefinders "ears", and 2 without rangefinders) and 4 trunnions (no barrels).

Until late 1941, the Lexington class aircraft carriers USS Lexington CV-2 and USS Saratoga CV-3 carried four twin 8"/55 caliber turrets.  The upper two turrets were fit with rangefinders.  The lower two turrets were not.

Install the turret with rangefinders in superfiring (elevated) positions.  Install the turret without rangefinders on the flight deck.

These turrets are not suitable for models of US Navy cruisers of World War Two.  Those ships carried 8"/55 cal. turrets of a different design (available separately).

Features:
overall dimensions accurately scaled from official US Navy drawings

six crew access doors with raised hinge, rain deflector and dog details
hex-head exterior bolts and rivets accurately sized, numbered and positioned according to photos of the actual turrets

From Wikipedia: "The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navy heavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 11 meters).[3]

"Mark 9: These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swing Welin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing 45-pounds (20 kg) of smokeless powder gave a 260-pound (120 kg) projectile a velocity of 2800 feet per second (850 m/s).[1] Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.[1][4]

"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range,[4] with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
