A lucky, if educated guess, and the help of the Birmingham Assay Office, has led to the rediscovery of Effie and Eleanor Ward, working together as jewellers/silversmiths.  Their mystery E&EW mark was registered at the Birmingham Assay Office on 7th March 1902, exactly the same day as Bernard Cuzner and Alfred H Jones registered their mark – I assume they all went to the assay office as a group of friends. Effie is best known for her enamels and as assistant to Arthur and Georgie Gaskin.  The mark is on a lovely, classic set of arts and crafts spoons. See more details at this link.
