Vintage’s Wagner Ware Sidney Magnalite Roasterette, model number 4263. It is a 4-quart or 4.5-quart capacity Dutch oven or roaster pan made from cast aluminum. Great Vintage Condition, please review all photos. My Grandmother had this for years and had taped the lid to the pot so it wouldn’t get lost, which is the marks you see on the pot.. it just needs to be cleaned. It was manufactured by Wagner Ware in Sidney, Ohio, and is known for its durability and even heat distribution. Magnalite cookware is crafted from a blend of aluminum and a unique magnesium alloy, which contributes to its superior heat conductivity
