A Pair of Vintage British Petroleum BP Industrial Tank Caps

A pair of heavy cast metal industrial tank caps associated with British Petroleum (BP). Each circular cap is cast with the block lettering BP on the outer face. The design includes two raised tabs on opposite sides, each featuring a small hole intended for security wire and lead sealing to ensure the integrity of the contents during transport or storage. The caps feature internal threading for attachment to tanker manifolds or storage vessels. This style of lettering and robust construction is characteristic of mid-20th century UK fuel distribution equipment.
