Antique embossed dug and washed medical, lab, bottle date coded 1930. Embossed CC and ounces POUR HERE ARROW pointed to applied top line. Side seams are uneven and faded that stop at the applied top with off-set seam to bottle lip. Blown molded glass bottle with the Owens and Illinois Glass merger mark and ILLINOIS spelled out on the bottom markings. This bottle was made just after Owens and Illinois Glass merger (1929) using an Illinois owned mold that is why it is double marked on this as the merger phase of the two different companies evolved into the combing of the already made mold from the two once separate companies. I also have Owens molds that have both marks as well as the two early glass manufactures with Owens spelled out and the IO in diamond mark with date and plant identification numbers, which is very nice to have for dating and identifying a glass bottle. Very thick, uneven glass bottom. No chips or cracks on the cleaned dug bottle with interior cloudiness that has developed a rainbow iridescent quality on the back side of the bottle. Air pockets in the glass with clear readable measurement lines. 5 inches tall, 1-7/8 inches wide,1-1/8 inches deep 13/16 inch across the tooled lip that has a flat small rim with a flared-out design screw tread top. Marked 3 oz but the bottle holds a bit more. Nice collectable condition rare, marked bottle. Nice example of the merger era making it a good historical glass making evolving bottle. Washed only with soap and water, I have not tried to remove the interior cloudiness,
