Pretty sure a medicine bottle but how old?
You can see its a very small bottle. Says 3i top front and Duraglas on bottom front. Each front sides have measurement markings. Seam on both sides go up to side top but don't notice that it's on top. Seam goes slightly across bottom then connects to a circle seam. On bottom it says OWENS, underneath that is a symbol that looks like eye with a circle in center. On left side of "eye" is a 1 or l and on the right side the #3. Any idea on year of this?
