Those are Griswold pieces made in Erie, Pa. To my knowledge, Wagner did not continue making the number 3, 5, 7, and 9 Griswold oval roasters, probably because Wagner already had oval roasters out the ying yang. While Griswold had the 3, 5, 7, and 9 oval roasters, Wagner had the 1, 2, 3, 4, 5, 6, 7, 8, and 9, so why would Wagner need another four more variations of the oval roasters? Thats my belief anyway, and I have never seen an oval roaster that Wagner made, from a modified Griswold pattern, has anybody else?
