So this was a gift from the neighbor who says he dug this at or near an old bottling plant that was in this lil town, not sure of any dates on that place, just looking for some input on a date and how the bottle was made! Not a screw top but does have 2 seams that dissipate after the neck, but also 3 seams running down the 3 corners. This is a machine made bottle or a mold of some type?? No markings kinda weird
