Looking at the two options under Question #8, it is clear (no pun intended) that this bottle matches refinement #2 which makes it highly probable that this bottle dates after 1920 and but probably no later than the 1960s.
We now have refined the bottle age range a bit more - between about 19.
Once the likely bottle age or date range is determined, some examples of other places to look for more information is provided.: -It is about 9" (23 cm) in height and 2 3/8th inches (6 cm) in diameter.
-It is made of thick, heavy glass for its size, weighing almost 1 lb.
The makers mark cinches the date in the 1940s of course, but without this marking the bottle date could not be refined further.
(Note: For more information on Owens-Illinois marks, see Bill Lockhart's Bottles and Extras article reproduced at the following link (pdf file): Owens-Illinois Glass Company (Lockhart 2004d).) deals primarily with cork versus screw top closures.
-There are molded (embossed) "swirls" on the shoulder and upper body of the bottle.
-The glass is clear (colorless) with just the slightest "straw" tint when looking through the thick portion of the base.
As the information under this question notes, ACL's in the U. date no earlier than 1933 and are still being made though most American soda bottles with this feature are from before the 1980s.
the makers markings on the base - we can still make a reasonable determination that this bottle almost certainly dates no earlier than 1933 (ACL, lack of bubbles) and could be as recent as the 1960s (straw tinted colorless glass).
