Sunbeam toaster from the 50s. Looks fantastic, has replaceable parts that obviously only need replaced at most once or twice per human life span, and it doubles as a mirror. Nobody enters my kitchen and fails to notice it either, which is a nice way to break the ice with first time guests.
One of the big issues is that the plugs are not polarized so they can be plugged in backwards. So parts of the toaster that shouldn't be can be live at mains voltage when not running. Electrical hazard. Don't use forks to pull your toast.
