Our farms are built in very populated areas, around apartment communities. This leads to some very unique finds in the dirt. Everything from old silverware, plastic toys, random trash, but also some cool historical items. Today while turning over some new raised beds, we found a small glass medicine bottle in great shape. I could tell it was old from the design and researched it a little more after reviewing the manufacturers mark on the bottom of the bottle. Turns out - this 55cc medicine bottle was from the Owens-Illinois Glass Company and manufactured in the later part of 1939!
The Owens-Illinois Glass Company was assembled in 1929 with the merger of the Illinois Glass Company and the Owens Glass Company, and a new manufacturers mark was used on the bottles. The mark was started in 1930 and was used through 1939, when in 1940 they added the "duraglass" label to the front of medicine bottles. This particular find has a "9" on the right side of the mark, indicating 1939 with the associated manufacturers mark.
