WW2 French 25mm Anti-Aircraft Shell Casing INERT

The WW2 French 25mm Anti-Aircraft Shell Casing INERT is an original brass cartridge case designed for use in French 25mm anti-aircraft guns during the Second World War. These shell casings were integral components of the widely-deployed Hotchkiss 25mm anti-aircraft gun, which served with French and allied forces from the late 1930s onward. The casing measures approximately 25mm in diameter and features markings on the base indicating manufacturing details, such as date and factory codes. As an inert item, it contains no explosive or live components and is safe for handling and display. Such casings played an important role in air defense systems, being used to fire high-velocity shells at enemy aircraft. This example reflects standard wartime production methods and materials, making it representative of period ordnance. It provides insight into Second World War French military equipment and is suitable for historical reference or collection purposes.
