NOT Milkglass. Nice Opalescent set. Looks like a Holly pattern. Old I think. Not sure who made it. Again I will ask @TallCakes to take a look.
Try searching "Northwood Paneled Holly" Looks like it to me. I believe this matches your set. https://www.ebay.com/itm/RARE-EAPG-...164162?hash=item2a4c907d82:g:Ga8AAOSwfcVUDhQz
