Here's a lovely old studio pottery jug but it has caused some differences of opinion.
I think it is from Devon around 1900 - 1920.
Will Axton the auctioneer valuer on Flog It! thinks it is/may be faience from the west coast of Europe (that's anywhere from Brittany to Portugal!) and may be as old as 1860.
What do the board members think? I can add more pictures if you need them.
