This pretty hand painted teapot is in excellent condition. It was made in the "Cottage Style" popular in the 1820's. I was able to find 3 examples of this New Hall teapot. One is on the website of the wonderful Norwich Castle Museum.
Another example is from page 202, plate 1207 of the "Directory of British Teapots" by Berthoud & Maskell. This is their description: "New Hall, c.1825, bone china , notched spout end, basket weave version, the handle with inner spur, decorated with enamelled flower sprays in plain panels and on the shoulder."
The third example is in Robin Emmerson's book, "British Teapots & Tea Drinking" page 268, pl.145.
The teapot is about 10-3/4" long. Both the lid and the pot ring when tapped. The finish is shiny and glossy. There are some shallow nicks & a shallow chip on the spout. There are some brown specks on the lid. No other faults.
It is not marked with a maker or pattern number.
