It looks like the record should be available through the State Historical Society of Wisconsin. They have a reference to it on their website - http://www.wisconsinhistory.org/vitalrecords/index.asp?id=18...
If you already tried to order from the State Historical Society, let me know and I'll see if I can find it there. (I work nearby.) Usually if it's in the Index, you can find it on the microfilm.
