I don't know if it is anything to do with electrics but there is a little decorative thing sticking out next to my light fitting in the kitchen. It looks like it's been painted over a good few times. It's only about an inch wide. I am planning on getting new light fittings soon and this is in the way but really not sure what it is. Its a 1930s house and when I moved totally unmodernised. Any help or ideas would be great.
