This is an Edwin Knowles Semi Vitreous china gravy boat with attached underplate. The pattern is of a narrow band of green leaf ivy with tiny dark berries. There is also somewhat faded gold trim. I have not been able to identify a pattern name. The gravy boat is 8 1/2" long and 3 3/4" tall. There are no chips, cracks, or crazing. The Semi Vitreous backstamp was used between 1920-1939.
