@pickerandagrinner@deborah63@seattlite@kategoring@francoise@agedrunner@dyanstevens@pennystot Morning, everyone. Louise and Dyan got it - it's a bathroom wall heater. Of course, it hasn't been in working order for decades, but back in the 1940s, space and wall heaters for the winter and window air conditioners for the summer were common. The heaters were turned off at bedtime or anytime you left the house, just to be safe. Thanks for visiting and playing along on the guessing game!
I came late to the party but was happy to be able to read what it was. I have guessed something along those lines but I have to confess that switch at the bottom threw me.
