I did my best to research this. But was challenged finding a website that dates the back stamp. The color is different from others I found- beige on the outside cream yellow on the inside. It is pristine- no nicks, chips, cracks or signs of use. Looks practically brand new. Bottom has impressed marking with patent 491517. Measures 12″ handle to handle, 11.25″ across the bowl. Lots of reflection in some of the photos off the glossy internal glaze.
