Vntg 16" Light Green Scrolls Trim Glass Oval Serving Platter ?Corning? 3lbs 4oz

Pretty Light Green Tinted/Pigmented Glass Oval Serving Platter. The glass is thick, dense, 3lbs 4oz heavy, like early Anchor Hocking. Rim is adorned with a raised scroll design for added interest. Sturdy & large enough for a turkey. She has worked hard and a few surface scratches in the middle but can't be seen when in use. NO chips-cracks and green glass is clear and haze free. I can't find anything definitive on the maker and have done some research only to find others have the same question. Corning was mentioned based on the stamped: "M-16 Made in U.S.A. 10" "No Stovetop or Broiler" But not definite, it could be Anchor Hocking or a number of manufacturers.
