Here is an Gladstone-LeLande Cobalt Blue battery jar I was lucky to find in an antique store. The lid is porcelain while the jar is steel instead of porcelain. It was sealed with a tar like substance and some of the carbon stuff was still broken up inside. I cleaned it up and removed the broken stuff plus tar. I have a picture of the inside bracket next. Really hard to find a whole unit and very pricey as well. Love all that embossing on the lid.
