Need a pic of the bottom of the bottle !! Also I can see the seam but the pic cuts the top off,, Need a close up of both sides of the entire bottle !! The seam and the bottom can usually tell you approx when made !! Hand blown,, it is not !! Possibly blown in mold !! If so the seam will stop short of the top,, don`t think thats it either but need to look at it !! Cant tell without better pics !!
