Hello, I am new here to your site. I am in the United States. I am wondering if any of you could help me with a question. I believe I have an Abraham Darby kettle/pot/cauldron from the 1700's when he invented coke-sand casting. I was going to sell it but after hours upon hours of exhausting research, I thought it best to reach out to others who might know better. I have seen the one in the Gorge Museum. This pot I have could be older. It had the definitive look of Darby and the 7 ears. Can anyone help? Thank you, Kimberly
