Hi, Maargot. Welcome to DC.
Unfortunately the cookware you are talking about hasn't been made by Corning for quite a while. However, there are several pieces up for auction on eBay. You might also check your area thrift stores for some of the cookware as well. I saw a 10-inch skillet and lid yesterday in my local Salvation Army thrift store. It was in good shape and they were only asking $1.50 USD for it.
Good luck on your quest.
