Owens Illinois or Wheaton Glass Company?

My father said he used this container in the 1950s to keep water in the ice box. I've been looking for manufacturer and am getting confused with multiple sources of information. On the bottom is 15,
I surrounded by an O, then an 8. The number 6 is by itself under the first row. Can you assist in identifying the manufacturer and date? Thank you.

The glass manufacturer is Owens Illinois. You need to see Bill Lockhart's article on the subject, found at
