Here is a CD 136.4 EIN [020] [No embossing] {MLOD} {Both Canadian and U.S. manufacture} SB (so-called Canadian Boston). I call it "unembossed," but there is a glass dot on the front crown (no numbers anywhere, though), so this may technically be unlisted. The color is some shade of Blue, and the Price Guide lists a number of options: Light Blue (150-175)--prolly, Sky Blue (300-350)--maybe, Sapphire Blue (400-450)—not likely, and Dark Sapphire Blue (700-800)—definitely not. Personally, I'd just call it a straightforward Blue, but interestingly that's not one of the options in the Guide. The major damage is about an inch-and-a-quarter of chipping on the wire ridges at the left mold line. In addition, there's another smaller flake to the upper ridge in front, some rubbing in the wire groove, a fleabite to the front crown, a tiny skirt flake at the rear base edge, and a small base flake. Also, there is some glass sickness: inside the skirt, around the rear two-thirds of the skirt, and slightly up into the crown in the rear. I expect a light tumble would get rid of most of the sickness, and the glass itself has excellent clarity as can be seen in the dome photo. But even as is, the insulator displays very nicely from the front with generous dome glass along with a distinct olive swirl in the right crown. Asking $185 shipped in the US. (a little more to Canadia or other locales). CK/MO.
