Set of porcelain fish plates (Eastbourne BN21)

A set of 9 plates plus 2 broken ones, a large serving plate (2 pieces broken off) and a sauce boat (handle broken off). They have been in our family's various attics for decades but hopefully someone can repair them and make use of them. These appear to be Antique Bonn Franzant Mehlem. They have the green tower Franz Anton Mehlem Hallmark Germany which dates them from 1887 - 1920
