Well, looking at the thickness of the pieces they are not the fine china of today. I have a couple of Japanese cups/saucers from 1800s which are much thicker than modern pieces. As I understand it most of the Blue & White that was produced 200 years ago came from China. Perhaps these items started out as ballast on ships returning to England from the Far East, and then accompanied settlers on the journey back here. Likely very well travelled.Does anyone here read 'willow' ?
