Lead weight. Cast pump seal weight, comprising a straight-sided flat plate with one curved end and one straight bevelled end, with a central waisted lug on the same side as the bevel. Patinated. The lug would attach the weight to the oiled leather seal of a water pump, which were operated manually until the 19th century. This is from a fairly small example. These pumps were used for major engineering and drainage works in the Humber region from the early 17th century, and the seal weights are often recorded with remnants of the seal attached, which points to their continued use into the 19th or early 20th century. This would usually have been agricultural, though an example from Roxby cum Risby, North Lincolnshire was perhaps used to take water from 19th-century ironstone workings. Suggested date: Post-Medieval, 1700-1900.
