Some other info (in case anyone cares!) The "7" to the left of the Owens-Illinois logo is a plant location code for Alton, Illinois. The "2" below the logo is a mold number ("mold cavity number" , showing position on the bottle making machine).
The " G- 9003" (I'm not sure if I got that number right? Kinda hard to make out) is a code number for that exact bottle design. SO if you find any other bottles made by Owens-Illinois that have the same exact G-number on the bottom, they will be the same shape/profile, regardless of the color of the glass or any embossed markings.
