Looks like a beer bottle to me.
The artifact looks like a speciality bottle, perfume, deodorent, etc. My grandfather and father both worked as "Stopper Grinders" in the glass industry before screw caps came around. Perfume and acid bottles were the last items to have glass stoppers ground into the necks oif each bottle(Some still do).
Before College, I followed them into the industry as a bottle/mold design draftsman in the 50's and we had samples of every bottle ever made by the company (Kimble Glass Division of the Owens0Illinois Glass Co). Someone in that company might be able to definitely identify the artifact.
