Description: | LeadPump seal Weights, as kindly identified by Dr Kevin Leahy. Two cast plates (a and b). Each object is a plate with one rounded end and an opposed straight edge, formed like the heel of a boot. The objects have bevelled edges, which for a heel would be angled inward and forward. The 'upper' surfaces bear integrally cast waisted studs with rounded heads of diameter 22-25mm. The larger of these objects retains fragments of thick (circa 4mm) leather in the waist of the stud, which probably passed through a slightly smaller hole cut in the leather. The leather would be oiled to serve as a diaphragm or seal in a water pump. Heavy duty pumps were available for major building projects from the later 17th century onwards, initially being manually powered, and were subsequently adapted to agricultural use. Numerous examples are held in the Carlile Collection of local detector finds, held at North Linconshire Museum, Scunthorpe. Suggested date: Modern, 1800-1950.(a): Length: 50.8mm, Width: 55.8mm, Thickness (clear of stud): 10.2mm, Weight: circa 275gms,(b): Length: 44.4mm, Width: 45.6mm, Thickness (clear of stud): 6.2mm, Weight: 125.91gms. Combined weight: circa 401gms.
