Built in '75, things moved and things added over the years. None of it by an electrician apparently. sloppy work, bad work, dangerous work. It's correct now.
My house has to be at least 100. It's just one hack job piled on top another. I've rebuilding the inside of this house slowly for 25 years. Everything's great except the service panel in the basement looks like something you'd see in India. I'm embarrassed to even call an electrician.
