The Royal Navy 1914-dated 3-inch brass shell case, produced by Kynoch, is a remarkable piece of military history from the early days of World War I. Kynoch, a prominent British ammunition manufacturer, was well-known for supplying high-quality munitions to the British military and allied forces. This 3-inch shell case, made for the Royal Navy, was originally part of the armament used aboard naval vessels, likely serving in shipboard artillery for anti-aircraft or coastal defense purposes.

Crafted from durable brass, the shell case is embossed with markings that include the date "1914" and the Kynoch maker’s stamp, signifying its production during the critical opening months of the war. The brass construction not only ensured reliability and resistance to corrosion but also made these shell cases highly collectible for militaria enthusiasts. Over time, many of these shell cases have been repurposed into trench art, further adding to their historical value.

As an artifact, the Royal Navy 3-inch brass shell case represents the technological and industrial efforts of the British war machine during the Great War, making it an essential piece for collectors, historians, or anyone interested in naval history or military ordnance
