During my research for this paper I went on a vacation to see family back in Wisconsin. And one day we slipped away to the Wisconsin Veterans Museum in Madison (if you're ever in Madison go there, you won't be disappointed). The last I had read about the cannon the 14th Wisconsin captured it was on the capitol grounds, which is directly across the street from the museum. I asked at the museum and they directed me to Camp Randall. They said there was a little interpretive park there with some cannon and it might be there. And sure enough, there it was. Of course this does little to solve the mystery but at least I was able to stand at the cannon.
