Cute Little Green Glass Bottle?

[Kurios1]

Howdy Folks. I found this cute little green glass bottle in a river. It measures 2 1/2 inches long by about 1 inch wide. It has a stamp on the bottom which appears to be the letter "O" with the numbers 3 1 3 underneath. Any ideas on what this is would be appreciated.

"O" FOR Owens, probably aspirin

I believe you nailed it mate. I searched through some images and the "O" also has the horizontal diamond running through it. So bingo on the Owens manufacturing the bottle. Looks like it could well have contained aspirin. I think I did see one bottle that matches mine identically but, it was in a group picture with no information. Thanks for the input!
