Manufactured by C. Allerton & Sons, @ 1859 - part of a child's tea set.

The plate measures 5.25" in diameter, the cup is 2" tall and 2.5" in diameter, the saucer/bowl  is 4.5" in diameter.

There is no crazing or discoloration but I did find 2 small chips on the cup as shown in pics. One is at the bottom of the handle and there is another along the rim.

This is not fine china, it was an inexpensive paste porcelain and there are imperfections in the glaze, 

Needs a good home
