Oldest toilet I've found and honestly that's only part of the goodness I've found in this building. Nothing could have prepared me for the diversity and rarity of these toilets. Where else can you find a Vitrite Ejecto, a regular sized Devoro, rounded Sanuses and Penryn in the same building?
Jones Hall was constructed in 1922 as the first Mens Dormitory on the campus. It would later be repurposed as offices and currently handles the International Affairs Department. The building itself is one of the original buildings, only built 10 years after Kirksey which was the first building.
When I was there, Kirksey and Rutledge Buildings were being completely gutted and renovated. I have no idea what they had and I wish that I knew because they were the only other buildings there outside of Jones and James Union that could have had substantially old fixtures.
Despite that, I'm glad I found these gems in Jones and can only hope they hang on for another few years but with the constant updating and upgrading of these old buildings, I have good authority on believing they'll be gone in the next few years.
