Jenkins used to advertise that one from a 19th century water main had been removed because the line was being re-routed by a water utility. The valve was cleaned up and put on display, and after a while, when everybody was tired of looking at it, it was put back into inventory and went back into the ground, probably to serve another 100 years.
