Corning Ware M-10-GR Ribbed Browning Skillet w/ Lid XC RARE

A RARE CorningWare USA 2 piece browning dish/skillet set. Under the handle is signed "Corning Ware M-10-GR-B  10" COOKER". Set includes: (1) 10" square casserole with raised ribs inside and original A-12-C Pyrex domed glass lid (cover). Perfect lustre all over. Dish and lid are in excellent condition all over. The dish has a small, SMOOTH chip on the handle as shown in the photos. This will NOT effect use.  I can not throw this away, so it's being offered at a DEEP discount.
