Been there, done that. I have checked every possible place that sells power points and sadly the only ones are available are pretty modern looking in bright white or black. If you are restoring an old house there are electrical components available, but not for caravans. If you do get some second hand ones make sure the contacts feel tight when you push a plug into it. If they are a bit sloppy the power point might end up like the one you have in the picture.
