AgX,
My 1899 brownstone was wired for electricity c. 1905. It was completely re-wired in the late 1930s and I had the wiring updated again after buying it in the '70s. There are still a couple of small dressing rooms and pantries that lack wall switches and use pull-chains. My darkroom isn't one of them, but I added a pull chain switch since the wall switch is on the other side of the door. Those switches are still common in US hardware stores, at least in cities like New York that have many old houses.
