Often bottles with the Owens Illinois mark on the base also have numbers which can help one decipher when and where it was made. Unfortunately this one leaves us hanging. Bill Lockhart has done some great research on O-I markings which you may find of interest but as I said, I do not think it is going to shed much light on this one.
I love the O-I mark in the cap - not sure I have seen that before.
My guess is that this one dates from the 1920s or 30s.
Don't quit your day job quite yet - this has some minor novelty value but no really bottle collector value.
