4450 b? Cream City Bottling Works Milwaukee, Wis
This picture shows a close up of the embossing on a pictured antique soda bottle embossed, CREAM CITY BOTTLING WK'S / S B (with a crown) / MILWAUKEE. What's interesting is that the cross above the crown - shown on the other bottle in the gallery - is clearly re-filled on this example. The only logical explanation is that someone complained about the symbol and that the mold was altered to avoid offending people. Very interesting to see that kind of PC activity on a bottle this old!
