Identifying the backstamps.
The numerous different backstamps used provide lots of useful information about the age of the piece, and sometimes the name of the range, the designer or the factory of manufacture. This information can greatly assist in the identification of the item and provide some history.
Displayed below are the majority of the standard marks found on both Hornsea and Eastgate pieces, but this list is still incomplete. Many of the marks are lacking photos at the moment and I would be gratefull if anybody with the relevant pieces could send me a snapshot. Please e-mail before sending to discuss size and format otherwise it may get auto-deleted at the server.
The backstamps have been given a Mark ref consisting of one or more letters followed by a number. The letter represents the manufacturer eg. 'H' for Hornsea and 'E' for Eastgate. 'SP' stands for special mark. The Hornsea mark numbers follow the convention used throughout the Hornsea Collectors Society to reduce any confusion.
