9649 B. Sturm West Bend, Wisconsin
This antique soda bottle has the washer ring in the center of the slug plate and the ring above the plate. This mold is believed to be from the Wisconsin Glass Company (but it is not embossed on this bottle). As is typical from this mold, there is a 'shadow' image of the center of the ring on the reverse side. The embossing reads, "B. STURM WEST BEND WIS." The blob is applied. Mrbottles found this example under water.
