I've seen normal size rectangular Mid Century electric warming trays before, but I've never come across one this large - a full 17 inches diameter. It's called the Electray, in bright harvest gold enameled metal with gold brass trim and handles. Height is 2-3/4 inches on three shiny brass legs. The tray comes in its original box, which is open but the tray doesn't look like it was ever used - no scratches, damage, heat marks, or discoloration. Made by Guild Metal Products of Rhode Island in the 1960s or early 1970s.
