Originally designed for the 20mm Oerlikon gun and other 20mm automatic cannons, these casings were widely used by both British and American forces during WW2. The 20mm Oerlikon gun, a highly effective anti-aircraft and ship defense weapon, played a crucial role in the air and naval battles. These shell casings were once part of the ammunition fired in defense of warships, aircraft, and ground installations, making them a vital piece of wartime history.

The OeZ marking was used to differentiate the semi-rimmed Oerlikon rounds from the similar looking (but not interchangeable) 20m Hispano. In British service, a “Z” stamped on the base of a case 20mm or below in caliber indicates that the case is loaded with nitrocellulose flake powder. This is opposed to the typical British Cordite “spaghetti” rod-type propellant.
