Dating tuscan bone china
A registered number was allocated to Wileman/Shelley for each design submitted to the UK Patents Office.The number is usually six digits long but can be less. The numbers are recorded in the Official Journal of Patents which is available at the Public Records Office at Kew, London, United Kingdom.
Early Shelley and Wileman pieces often displayed the registered number rather than a pattern number.
For china produced in 19, the letter “A” was placed under the word “England” on the backstamp. The Shelley company was taken over by Allied English Potteries in 1966 and thus no further letters were used.
This system was not used consistently during 1962-65; thus not all china produced in these years bears either the A or B.
The UK Club has an extensive discussion of backstamps which they have shared with us.
This page shows many of the known backstamps which were used by the Wileman family potteries to include predecessor companies such as Elkin Knight: forth below are some of the most common backstamps used on Fine Bone China and miniatures.As noted, many variations of the above exist, usually occurring when Shelley or Wileman added a particular pattern name and/or number to the backstamp.
