Looks BIM to me also[8|]ORIGINAL: old.s.bottles
That bottle is blown in a mold then the lip is hand tooled, which is why the seam does not go to the top of the bottle. If it was made in an automatic bottle machine (patented in 1903) the seam would go to the top of the bottle like modern glass bottles. After handling some more bottles you should begin to recognize the characteristics of both quite easily.
