Bottom of blue bottle, clear codes

Hi- I am new to this and wondering if anyone can help me understand the numbers on this bottle. Would love to get a sense for how old it is. Thank you!


  • Base markings like this are proprietary to the manufacturer, and there is not much known about most companies with the exception of Owens-Illinois.

    One can say this is a modern machine-made bottle that is most likely no more than about 30-40 years old

  • Thank you! I was hoping one of those numbers indicated the year. Was thinking 1980s but not certain.
