A Norwich cloth seal with the letters in a well known style on one side (although this particular seal seems a bit unusual) and the other side shows the surname initial of the 12 wardens of Norwich & Norfolk for that particular year. It is normally possible to identify the missing letters from the Norwich Mayor's Court Book held at the Norfolk Record office under reference: NCR Case 16a/24,(fol. 68v). Unfortunately no record remains for this set of initials.
See the 'Worsted Reformed' seals that were attached to the other end of these cloths.
