If it's a Custom Imperial,it has "Electri-Clean Plus" where the left oven has panels on either side and the bottom that are removeable to place in the right oven and clean along with it.There was also the "Meat-Tender" thermommeter that was a probe to give ine the ability to sellect the doneness of a roast from rare to well done.I doubt seriously if this range on ebay had it with the unit. It was either lost,missplaced or disscarded by the original owner.
