Does anybody know for certain which is the correct tenor weight for Peterborough Cathedral, 21-2-20 (Dove & RW 3938) or 21-1-20 (TowerBase & RW 3976)? Also if St. John de Sepulchre, Norwich tenor weighed 8-3-22 (lost rings) would it follow that this should be the weight shown in Dove and TowerBase for Erpingham and not 9½cwt? Nick
