37mm Inert Anti-Aircraft or Anti-Tank Projectile and Casing

This item is a 37mm caliber military projectile seated within a brass cartridge case, likely dating from the World War II era (circa late 1930s to mid-1940s). The projectile itself features a solid, ogival-shaped head made of steel or iron with a darkened, oxidized finish. Below the steel tip is a prominent rotating band (driving band) made of copper or a copper-alloy, which is deeply stamped with the markings 'LOT 1075 38'. This suggest a manufacturing date or lot identification from 1938. The projectile is seated into a cylindrical brass casing that exhibits a dull, aged patina with significant surface oxidation, darkening, and minor pitting consistent with long-term storage or handling. The construction is robust, designed for high-pressure firing from an anti-aircraft or light anti-tank gun. There is a visible horizontal gap where the projectile meets the mouth of the casing. The overall condition shows signs of age and wear, including surface abrasions and discoloration of the brass, but the stamped markings remain legible. It appears to be an inert display piece, often referred to as 'trench art' or a military souvenir, though it should be handled with professional caution regarding its internal components.
