The seam goes almost to the neck so from what I see I'm thinking very late 1800's to early 1900's If you could resize the picture that would help. Also is there anything on the bottom of the bottle. As a rule the further up the neck the seam goes the later the bottle. Notice I said as a rule on the seams. There are exceptions. I think they started making bottles by machine in the 1920's On machine made bottles the seam will be narrow and goes all the way up the bottle .
