Illustrated among the pics on this page is the base of a bottle made at the Columbus, Ohio facility (plant #18) with a date code of “7” which in this case probably stands for 1937.I don’t know how late the word “OWENS” was embossed as a trademark on the base of those medicine bottles.We gather information from public sources to create complete and current Background Reports & Reputation Scores for everyone.
IMPORTANT NOTE: Many liquor bottles and flasks made by Owens-Illinois have a DIFFERENT mold code configuration on the base, as compared to the way the numbers are arranged on most other types of bottles they made.
Typically, it is marked with a number called a “Liquor Bottle Permit Number” followed by a dash and a second number which is the date code.
However, there are some exceptions to this general rule, and single-digit date codes were also used in later decades along with the later “I inside an O” mark (but without a period placed to the right of the code).
Most bottles from the late 1940s into the 1950s and 1960s have two-digit date codes.
