The Frigidaire Radiant Wall Broiler Pan was introduced about the same time as the Pull 'n Clean oven. It was a two piece affair with a deep aluminum pan with a chromed rack in the bottom and Bakelite handles on both sections. The pan sat on a shallower pan that had cold water added to it, the purpose of which was to cool the fat that dripped into the upper pan. In use, the pan was used on a set rack position in the master oven and the Broiler Grill dial was used to select the intensity of the heat input: high for rare and lower heats for well done. The high sides were intended to keep the oven clean. I don't know how well the pan broiled or how much fun it was to reach past the high hot sides to flip burgers on the wire rack in the bottom of the pan. Either pan could be used as a roasting pan and they could be combined and used as a covered roaster
