    • The axle-mount was cast from a high lead copper alloy (Cu-85%, Pb – 11%) with 4% of other alloying elements present (Zn, Sn, Sb and As). A high lead alloy would be an excellent choice for an axle mount as the lead would act as a lubricant. According to Brownsword’s classification the axle mount composition corresponds to that from the Coastal Region dating to the 13th-14th CE. The presence of iron staining in the axle-pivot suggests either an iron axle or a wooden axle sheathed in iron. The diameter of the axle would be circa 50mm (2 inches). McDonnell, G. (2021)
