Comes from my private collection . Selling ONLY because of health problems . This is a 10 inch BLACKLOCK Foundry Cast iron lid . They made VERY FEW items . The lids they made had the tall lip around the outer edge for coals . THIS one as you can see DOES NOT have that lip . I have talked to some of the BIGGEST cast iron collectors in the US and NOT 1 has seen THIS LID . I was told by one person , that it could have been one of the first lids like this made and then the foundry bur...nt down . I have NEVER tried to clean it . Everyone I talked to wanted to buy it if I ever got ready to sell . WELL the time has come . I am taking a chance starting it at a NO RESERVE . It WILL go to a new home . I have owned it for a few years . I picked it up years ago at a auction . It is one of my favorite items I will be listing , BUT I have no choice but to sell . I hope it goes to someone that will enjoy it for years to come , as I have . This COULD BE the ONLY ONE OUT THERE ! It has a beautiful gate mark on bottom . Has nice ring to it when thumped . NO cracks . I am NO expert on cast iron BY NO MEANS . I don't even collect pots , lids , etc. If anything , I'm a wash pot person . PLEASE look at ALL my pictures . All pics were taken outside . It was wiped down with some type of oil when I bought it . I wipe it with cooking oil every few months . What you see it what you will get . So again , PLEASE look . AND as always , selling AS-IS because of age . GOOD LUCK . Winner will be owning a piece of history .The founder of Lodge (Joseph Lodge ) started Blacklock .
