Two sets are required to complete one model. This set of two turrets (more properly called "gunhouses") is designed to accurize any 1/700 scale USS Pensacola CA-24 or USS Salt Lake City CA-25 heavy cruiser model kit. Depending on which kit you own, some adjustment may be needed for best fit. The US Navy installed two 8"/55 caliber Triple-gun Turrets and two 8"/55 caliber Twin-gun Turrets to ships of the Pensacola class heavy cruisers of World War II fame. Please use your favorite brass barrels or your kit's parts.
- overall dimensions precisely scaled from US Navy O.P.1112 (2nd Rev.) "Gun Mount and Turret Catalog" drawings dated 15 January 1945
- correct gunhouse roof geometry (slightly different for each gunhouse)
- accurately shaped armored rangefinder hoods
- four crew access doors and 172 hex-head exterior bolts properly positioned, sized and correctly placed according to photos of the actual turrets
- separate trunnion, slotted for your favorite brass barrels (not included) to allow you to position the guns to any realistic elevation from -5 degrees to +40 degrees just like the real turret

From Wikipedia: "The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navyheavy 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."
