A cast lead cylindrical object with nails projecting inwards from the raised rim. It was found by a pair of detectorists in September 2020 on a Roman site near Rudston. It is thought that it is the waterproof end of of a barrel shaped tank, cistern or pump base. It is suggested that the storage of water would have been necessary to allow the year round occupation of the site in the Roman period.
Due to its weight, it took two men to lift the object.
