This distinct base scar now is easier to illustrate than describe; visit suction scar for a picture of the mark which exhibits the symptomatic "feathering" that clearly suggests Owens machine creation (exact same graphics was down the page kept). This level is actually unique towards suction techniques which feeds windows to the bottom of an Owens maker's parison mold. (mention: a film video revealing this process in action is linked in the bottom of this package.) Sucking scratch cannot be created by feed and movement automated devices (for example.
