2.20" diameter, of uniform thickness, rather than a sphere with cylindrical central void as with European examples. While it has significant weight as is, it almost surely was backed, probably with lead, to supplement its weight and increase energy upon impact. See Nicolle figure 493a for an illustration of a similar example which, however, gives no indication of its construction. This example is unique in our experience of having examined dozens of specimens from the Crusades battle sites. Sound stable excavated condition with the delicate edges of the openings intact.
