Opinions on this bottle

Just found this on an old farm and was wondering if anyone here could tell me how old it is or what it might be worth. I think it's an owens-Ill. company bottle, but I'm not even sure on that. I don't know much anything about bottles. If you can't see from the pic, the bottom has a 7 then an I inside a circle and a diamond and on the other side of that is a 1. beneath the circle/diamond is the number 12. Thanks for any comments.
