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.

Many millions of insulators were made at Muncie, up to 1967.

(See my webpage on Hemingray Glass Company for more information on Hemingray insulators.) Known as Owens-Illinois, Inc.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.On many bottles, a single-digit date code along with the diamond/oval/I mark may indicate the 1930s.From information compiled in Bill Lockhart’s article (link below) on Owens-Illinois’ date code markings, it appears that, on containers with this earliest trademark, if a single digit date code (such as “O” or “1” placed to the right of the logo) the chances are very good the bottle in question dates from the 1940s, especially the 1940-1947 period.For a page with some of the principal plant code numbers used on bottles, courtesy of Dick Cole (fruitjar.org), click here .
