I have not seen so much information on Royal Vale anywhere else online. I collect bone china from the Staffordshire potteries in England and I saw some beautiful Royal Vale being auctioned the other day, but didn't know anything about the backstamp. Now I know a lot more.
I am trying to get hold of the following books which are supposedly the best authorities on the history of bone china and fine china crockery in general and they are Geoffrey Godden's Encyclopedia of British Porcelain said to be better than any other reference books. For 18thC and early 19thC china manufacturers, the reference book used by museums and antique experts is W.B.HONEY'S old English porcelain.
