Pressed Glass Creamer

Hi, this is an old pressed glass creamer with an applied handle. I have searched high and low to try to identify this, and am hoping that someone can help point me in the right direction. It is 4 1/8" h. and the base has seven sides. It is very heavy and weighs 1 lb. 3.3 oz. (546 g). I have put this in these categories for lack of a Flint glass or Unknown glass category. Thanks in advance for any help.
