WW2 British 2 Inch Mortar Round Tail Fin

The WW2 British 2 Inch Mortar Round Tail Fin is a component designed for the 2-inch mortar, which was widely used by British and Commonwealth forces during the Second World War. The tail fin is typically constructed from stamped or cast metal and is attached to the rear of the mortar round. Its primary function is to stabilize the round during flight by imparting spin and ensuring aerodynamic balance. The standard 2-inch mortar served as an infantry support weapon, capable of delivering high-explosive, smoke, and illumination rounds over short distances. The tail fin includes slots for vanes and may feature mounting holes or crimping marks where it was secured to the body of the round. This item reflects the engineering priorities of the era: ease of production, reliability, and effectiveness in combat conditions. It is of interest to collectors and historians focusing on British ordnance and infantry weapons of World War II.
