From a bit of research the backstamp indicates that these the foxglove design with the star backstamp and the addition of fine bone china were used from 1920 to 1932. There is no pattern number on the Foxglove design items that I have. I am no porcelain fundi so I would recommend that you follow up with your own research should you be interested. Please look at the pictures carefully and dont hesitate to ask any questions.
