Hello I have a small cup and saucer which came with a small piece of paper stating: Tiefenfurt - Silesia c1808 - P Donath The first factory was already established in 1808 by Johann Heinrich Nicolai Matthiesen, and P Donath was a managing director who became the owner in 1891. It has no markings which I can see. After searching online I can't see anything similar, perhaps I'm using the wrong search... or they are something completely different and the piece of paper has nothing to do with it! Edit: Had another look on t'internet... and it looks similar to Jackfield?... Can anyone help, it would be most appreciated - thank you!
