Picked this Favorite Piqua Ware dutch oven up at an auction Saturday. It is coated in white enamel and is the same size as my Griswold #8. Beside the logo in the picture, the only other marking is 3F8D on the underside of the lid. I've never seen an enameled Piqua piece of any kind before, and can't find any information on this particular dutch oven in enamel. I was hoping someone on here might have some insight. Is this piece rare? Valuable? It is in pretty decent shape, with some light chipping and stains on the bottom mostly. Really a cool looking piece (especially like the iron ring) that I was excited to get.
