Have a cast iron rendering cauldron stove; stands approximately 42″ high; the cauldron is removable and sits above the fire box. which is held up on legs. I have been told it was made for hog rendering fat. Marks on front reflect “Cribben & Sexton Company Chicago ILL; 30 gallon; 1856, This piece has never been used in almost perfect condition. Probably weighs around 250 pounds. I have seen one sitting in Union Oregon in a museum which was in bad shape. Have also seen the cauldron portion in NE Washington but have never seen another one. I have been trying to find something about it on the internet with no avail. I’m looking for possible value so I can sell. I do know its extremely rare
