glad you got there in the end Chris - Obviously it came subsequent to my earth coloured piece, which Colin Green was kind enough to id for me, a part of his reply which did confirm that AB used silver chloride in the early days. I can appreciate the problems this example must have given - a colourway and shape that look Maltese - and a recessed pontil that shouts AB. Great shame you are missing a stopper. So in all probability Michael Rayner was responsible for your small pot and the larger vase of mine that Greg links. Not sure if we're supposed to apologise to Stew for sidetracking this thread, but it is all related I guess.
