The housewatch in those quarters has been there forever. Of course when I was a kid there was no enclosure. It was just a a raised platform, desk, wooden chair, blackboard and bells, with a railing around it. And a radiator to try and keep warm in the winter.
Long ago memory... Keeping score for some game with chalk on that spot between the apparatus door and the visitor's door... Nothing malicious, just kids being kids... When we finally got bored one of the men appeared with a pail of water and brush and told us to clean the bricks. Just one of those moments that sticks in your brain forever.
