• Military Stamping: The base is clearly stamped with the official British Broad Arrow / King\'s Arrow property mark and the production year 1944.
• Original Label: Retains its original paper \"Directions for Use\" label on the exterior shell, detailing care for hot and cold contents.
• Condition: Excellent historical condition. The black crinkle-finish metal body shows great patina with minimal wear. Includes the original oversized wood cork stopper and the metal top cap/cup.
• FLAWLESS GLASS LINING: Crucially, the internal Pyrex glass vacuum lining is completely intact with absolutely no rattling or cracks. Most surviving models from this era suffer from shattered internals, making this fully whole specimen highly collectible. See photos for condition no rattling from the inside glass visible around cork
