History of Norfolk — Chapter 20
“ The wardens have full power to search all worsteds in Norwich, Suffolk, and Cambridge, as well in the looms as out, and to convene any persons that are faulty or disobedient to their ordinances, before the mayor or steward, who shall punish them at their discretions; and every man shall put his proper mark on every piece, under pain of forfeiture. ”
