6620 ? M. Weber & CO., Oconomowoc, Wisconsin

This is a fantastic bottle from a company that only recently was re-discovered. I am proud (and lucky) to say that I found the first known modern example in March of 2000. (Maybe a hunt story is in order?) Since then, a few more examples have turned up. Nonetheless, this is a very rare bottle. The bottle is embossed, "M.WEBER & CO BOTTLERS OCONOMOWOC, WIS." The bottle pictured was found by Mr bottles who allowed me to trade-up the one I found. Outside of some typical inside mineral haze, this bottle is mint. One other small note. The bottle has a "G" on the bottom but no mold maker marks. Does anyone know what this stands for?
