This line up of big signals has: on the left a U-274A No Name. It stands 4 1/4" tall and has a black/gray glaze all over except the base edge. The center piece is a U-274 embossed: O.P.CO on the top of the wire ridge. The color is a little darker than this flash photograph indicates. Yeah, it's chipped, but it is a tough one to acquire. It is dry process porcelain. The tall guy on the right is another U-274A No Name. The photograph color is correct. It is wet process porcelain and has an unglazed pinhole and base edge. The OP CO piece was purchased at the Mid-Ohio Insulator show in Springfield, Ohio in 2001. Photograph by Jeff Hogan.
