Two Wisconsin Central cabooses sit side by side on the tracks near Fourth and Appleton Streets in this 1971 photo. Because of the time frame, the thought occurred to me that perhaps this was one last inspection to see which caboose would be accepted by Menasha to display in Smith Park. I cannot vouch for that idea but magnifying the picture indicates that the caboose on the right is indeed labelled as "104," which IS the caboose number of the one in Smith Park. The gentlemen pictured below just might be the same fellows exiting caboose no. 104 in the photo above.

The caboose is in need of repairs and there is currently a fundraising drive to provide for its upkeep. The article at this link showcases this effort:
