23 7/8” diameter, domed, with rolled and chevron roped edge. Small central spike of compressed form. The surface quit bright and smooth with pitting and remnants of annular ring decoration in protected areas, indicative of robust cleaning. This is an infantry shield, sometimes called a target. Its weight dates it to the earlier period of firearm use. It was carried by a warrior in half armor armed with a broadsword. See Arms and Armor in Colonial America, pl.135 for a very similar example, one of a group in the Tower of London (at that time) believed to be English.
