This may be Coalport's earliest* version of their classic Chinoiserie pattern which they called "India(n) Tree". The fluted cups with "Old English" handles date this set to c 1825-30. You will notice the lack of border, which we are used to seeing on later versions of "Indian Tree". The pattern is printed in puce and hand enameled.
These early 19th C porcelain pieces are in excellent condition. There are no chips, no cracks, and no repairs. All three ring nicely when tapped.
This cup form with the flat topped Old English handle is "typical of Coalport", according to Michael Berthod, in his book "A Compendium of British Cups".
The shape is shown on page 138, plate 765 of that book. There are no marks or pattern numbers on this set.
* Note: many writers date Coalport's "Indian Tree" to c. 1801. Michael Messenger, in his book "Coalport" says an 1820 date is more likely.
