Hi Tara. I agree, that's a wonderful pot. While patterns were often made by more than one pottery, I have been looking through what Swansea sources I have and not located this particular design. One did note however that the factory produced a number of different shell patterns. What Swansea coffee pots I have seen appear to be a little more squat than this one, with a thicker "ankle". But it does look like a pattern that pottery could have produced. Lacking a mark or any documentation it's hard to make an attribution. Still a great pot! I'll let you know if I come up with anything.
