We did a renovation on a school built in the early 50's. One classroom still had the original GE school clock on the wall,(bakelite base with glass bezel) hung on the clock outlet, in working condition. The others have been replaced with more modern plug in's or cheap battery operated ones.
The school facilities director said I could have it if I bought a new battery one in place of it, so I did. Now it's hanging in my shop.
