Notice: this model is designed for Best Detail using "Fine Detail" acrylic plastic, the best material available producing exceptional detail and smooth surfaces. "Fine Detail" acrylic plastic is a good choice for static display models. "Fine Detail" acrylic plastic is comparatively brittle. Therefore, it is not recommended for Radio Control models. Compared to "White Natural Versatile Plastic", a kind of nylon available separately, "Fine Detail" acrylic plastic produces sharper edges, details that are more defined, and the surface is much smoother with this product. "Fine Detail" acrylic plastic is sandable, cuts easily, and is compatible with more kinds of paint.

This turret is not suitable for USS New Orleans CA-32 or USS Astoria CA-34 and other ships of the New Orleans class. They had a differently shaped triple 8" turret.
A combination set of Twin and Triple 8"/55 cal. Turrets is available separately for USS Pensacola CA-24 and USS Salt Lake City CA-25.
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).
"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). Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.
"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range, with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
