Zwietush Milwaukee Wisconsin Spring stopper bottle

Early aqua spring stopper soda embossed on the front "O. ZWIETUSCH MILWAUKEE." This antique Wisconsin bottle was found upriver from where we live now by a dive buddy looking for bottles. Another friend found the stopper in Madison on a hunt for Lindstrom bottles and gave it to me. It's an 8.5 of 10 luckily with the stopper. I got this one in about 2002 from Tom Fredrick who found it in the Bark River near my house!!! Thanks Tom!!! Jim Koutsoures found the actual spring on a bottle dive with Bob and I to Madison. How lucky am I to have this complete bottle and closure. Thanks Jim!
