This Corning Ware casserole, in the April pattern, is in like new condition.  Very clean with no chips, cracks, or breaks.  The only marks I see on it are slight shelf marks on the bottom that should be easy to remove.  The casserole is 2 1/2 quarts and has a Pyrex DC1.5C glass lid.  This pattern was only in production from 1977 - 1979.  A beautiful piece of Corningware!
