A large heraldic plaque of the late medieval period. The plaque is lozenge-shaped, made of copper alloy, and has four rivet holes for attachment, two of which retain rivets. Heraldically, the lozenge is divided quarterly per saltire, each quarter seemingly depicting Ermine, on a fess gules three bezants, although the details are somewhat unclear and the bezant colour is uncertain. The arms have not been traced at the time of validation.
