974Terd Found a small medicine bottle yesterday that used a cork stopper and was marked 3iv. Can anyone help date the bottle?
Chris Thanks for posting.About the best you can say is second quarter of the 20th century. If you have not already seen this forum post, take a look:https://forum.antiquebottles-glass.com/discussion/comment/3738#Comment_3738
974Terd I did a little research and learned that the “O in a Square” makers mark is from Owens Glass Company and the mark was used between 1919 and 1930.
