The cord is twisted cloth covered wire. By the way it is attached to heater I would say it's original. It is wrapped with cloth tape at connection very neatly done. Still very tight and heater works, so I'm not taking it off. Someone had added a more modern cord to this cord to make it longer. I took that cord off and put a new old style end on it.

Thanks for the reply Randy. And good news. Amazing that the heater still works.
