What was this bottle used for
Bottle is 9 inches tall and approx 2 1/4 inches across. Has seam up the sides that stops at the neck of bottle. The word OUNCES is arched across top/side with ounces marked underneath it starting at 12 to 1 with 1/2 marking lines too. The bottom has no markings, but does have a distinct indentation. I'm sorry if these pics are not the right size. I'm not too computer savvy. I'm just interested in what this bottle was used for. Thank you.
