"Thank you for the pictures. You can just make out the 'Wedgwood &', and underneath 'Tunstall', which is useful.
I'm afraid that I can be of little help on this occasion as the ware in question is a product of Wedgwood & Co not Josiah Wedgwood (& Sons).
Originally founded around 1832 by Enoch Wedgwood in Tunstall, Stoke-on-Trent (Staffordshire), this factory (Wedgwood & Co) had nothing whatsoever to do with the firm known formerly as Josiah Wedgwood & Sons Limited, until 1980 when we were forced to take them over because of the ongoing confusion with the use of the Wedgwood name. At the time of the takeover we were advised that their records had been destroyed in a series of fires in the 1950s, therefore we have no archive or other documentary material with which we can assist members of the public with enquiries relating to this former manufacturer. You may however find this website of some use:
We didn't know that before!
