Had this one in a box in the closet. It is the EIN  embossing. Front: 0-4/ HEMINGRAY/MADE IN U.S.A. on the back: D-512. The color is a more Pyrex looking dark orange carnival. The glass itself appears to be clear, but the PG doesn't indicate any clears, so it might be the blue tint. Funny how it has minor amounts of a black tar substance OVER the carnival coating. No evidence of wear on the wire groove or on top.
