This is the Hartford Faience A157. Once thought to be the only multipart style made by Hartford Faience, this piece stands 6" tall and is only one of two known in the hobby. Recent research points to evidence that Hartford Faience made five different multipart styles. The A157 is the first of those found thus far. There is a very faded HA157 marking on this piece.

2014 UPDATE: More A157s have been recently discovered in other collections. A few were found still in use in New England.
