5726 Henry Schinz Milwaukee, Wis. (AGWL)
Another antique soda bottle with heavy inside mineral deposit from the water. I used to find this a little annoying, but now I think it is part of the character and history of the bottle! This blue aqua example is embossed, "HENRY SCHINZ BOTTLING Co. MILWAUKEE." There is an "H.S" on the bottom and a glassblower of AGWL (reverse hub).
