Lead weight. Cast sub-rectangular water pump seal weight, with a bevelled sub-rectangular lug on its lower side to engage with the oiled leather of the seal for a pump chamber. This position corresponds with a round hammered patch on the upper side, probably where the weight has been pounded through the aperture in which the bevel would assure a snug fit. The lug has been deliberately split by a heavy blow, probably to increase its splaying to improve the seal. Water pumps were used for engineering and drainage works in the region from [at least] the 17th century, and in the improvement of land drainage and water management at later times, which is probably the context for this example. Suggested date: Post-Medieval, 1700-1850
