This signal style is an unmarked G.P.Co. The color is unusual, a light gray with darker gray bands at the base, wire groove, and dome. There is also a sprinkling of blue specks just visible thru the glaze. A small strip of fire brick stuck on the base adds character, as well as a glazed over chip. A couple tiny flakes are the only damage I can see. A really neat piece! asking $35.00 postpaid. Thanks for looking!
