This product comes from renowned Polish model accessories manufacturer Master, a synonym for top quality and incredible detail reproduction.

Historical background and application

8"/55 (20.3 cm) Mark 9 is one of the most famous American naval guns of the interwar period and World War II. This gun was mainly used on heavy cruisers such as the Pensacola, Northampton, Portland, and New Orleans classes, which took part in the most significant naval battles of the Pacific, including Midway, Guadalcanal, and Leyte. The Mark 9 guns—an early, heavy version of the 8-inch gun—were distinguished by a characteristic, massive silhouette. Later versions (Mark 10, 11, 13, and 14) were externally very similar, so the barrels in this set are also suitable for numerous US Navy ship model versions from this era.

Material and workmanship

The product is made from precision-turned brass, providing exceptional detail, high resistance to damage, and ease of assembly. The set requires no cleaning of seams typical of plastic barrels, offering near-instant readiness for installation. These barrels are dedicated as replacements for original parts in plastic model kits, greatly enhancing the realism of the finished model.
