One of the 'immovable' items on this little wall in my house is this entirely mechanical timer-switch which ultimately controls the largeish fan/motor mechanism located in my tiny "attic" (pic #3) which resides up there just over the self-opening grille slats (pic #4) on the ceiling of my little central hallway, also immediately over said little wall. :-)
The fan, as it was designed to do, is capable of creating *quite* the refreshing draft of fresh cool (-ish, nighttime usually) air into/thru the house, as it 'sucks' outside air in thru any open windows/doors, exhausting it thru the outside eave vents. Such fans were apparently rather common features for 'southern houses' built in the mid 1900's, in an era where 'household air conditioning' hadn't quite become perfected yet. Many since have been removed/disabled, but I'm actually very happy that my house still has its one -- the thing really *IS* a kinda wonderful household appliance...
The switch itself is actually not original to my own house (the fan is, though) having been recovered from another structure elsewhere, but I'm otherwise certain it is of the correct vintage as I've since recovered remains of another exactly similar switch from a different de/construction project at another house in my neighborhood.
Early 1950's, made by MINNEAPOLIS-HONEYWELL, the switch has a fully mechanical springwound timer mechanism that tilts a glass mercury switch one way or the other to actually turn the fan motor on/off. It is in original operational condition, though I did repaint its exterior housing [w/Rust-Oleum 'hammertone silver'] because its original radiator-goldtone paint refused to clean up to my liking. Its original finish still exists on its timer dial face, front logo, and on its side where I masked the original (if grungy) color/lettering when I repainted it.
