Got a #8 skillet and cover and what I now know is a Scotch bowl with a cover. Her family called the bowl a dutch oven. However it has a round bottom not flat. Underside says ERIE 781 #3. Looking forward to learn cast iron cooking with them when camping.
What I'm really looking forward to is cleaning them with electrolysis method I found while researching these items. Oh Man!! How cool is this. A chance to mix together water, metal, and a good few amps of electricity too!! Plus generate some hydrogen gas while I'm at it. Can't get much more exciting than that.
