Duke, The S stands for the Streator Ill. Plant. I do not know what the 6 stands for. Possibly a moldnumber? OT Digger, Those are the dates I have for AB Co. There was a maker mark of AB which was used on handmade bottles. The maker is unknown. These references are coming from " Julian Toulouse, Bottle Makers and their Marks" Hope this helps, Kelley
