Vintage O'Brien & O'Brien Chicago 10 Cast Iron Chicken Fryer W/Lid Rare Find. Nice hard to find set. Could use a good cleaning, the white stuff on the outside of the pan and lid I think is wax. I scraped a small section of it off to see if it would come off and it did. Both pieces show signs of wear.If you would like more photos or have any questions please let me know.
