Gina, your lovely Staffordshire teapot is included in the TCC Database of Patterns and Sources as entry 13403, and is titled "Palladian Mansion and Church". Things get a bit complicated as to maker. Our current example is unmarked and there is not an attribution to a particular maker; the pattern is related to a series, "Variety", attributed to the maker Ralph Hall, but Hall is not known to use an impressed anchor mark. This could suggest Davenport, but that is not at all definitive. Below is what we actually have to say about this pattern.

Teapot, 11.25 inches handle to spout and 7.5 inches high. It is unmarked but has the same border as the marked saucer illustrated in "Variety" #01, pattern #10483. As with the other views, this scene of a large Palladian mansion in front of a neoclassical church appears to be based on a real view, but so far none have been identified. Royal Hospital of St. Katherine in Regent's Park, pattern #1727, shows a sugar bowl with the same border and pattern treatment, and marked with an impressed anchor. As it is not known that Ralph Hall, the maker of the Variety series, ever used this type of mark it leaves open the possibility that more than one maker produced the pattern. Pending further information that pattern and this one remain Maker Unknown.

Separately, I'll forward a PDF of our Database pattern.
