Ciao Ned, so sorry for delay in thanking you, your help was great. Look what i found about Neva pattern and unknown maker. I was looking everywhere in English pottery but one maker is Italian, Ceramiche Pera ! I laso found with same pattern another maker, the backmark is identical to the Ridgway one but there are the letters WJL or WJ&L. Any idea of the manufacture? once again thank you so much for your reply. Have a great day . Giovanna
