Brigandine plates. 14 small and 2 larger plates from a brigandine. The two large plates are 6 1/4 and 6 1/2 inches long, and just over 3/4 inches wide. They have a row of closely-spaced rivets at the upper edge. The rivets are app. 3/8 inch on center. The smaller plates are also slightly over 3/4 inches tall. Most are app. 1 1/2 inches long. The smaller plates fall into 2 types. 13 are rectangular/trapezoidal with (generally) 2 rivets at the upper edge. The last plate is oval and has 3 rivets which are of a different form - larger, flatter heads. The plates vary signifcantly in curvature. Many seem to have been flattened or bent after their working life.
