I very happily picked this up today, and am really looking forward to cooking with it. I've not been able to find out anything about the lower case "ac" inside a circle imprinted on the top of the lid. I think it's about 7 1/4 quart, and is the same color as the flame orange Le Creuset. It has some crazing, and seems like it has more than a few years under it's belt (lid?), though still has a lot of life left!
Any info out there? Would love to learn more! :) Thank you!!
