We have a couple of pieces from the wife's grandmother, and have identified one as 7-inch Wagner Ware "low-profile" skillet(?) with heat ring from late 20s or early 30s. The other, which probably is from roughly the same era, has no visible identification other than a "5". It's a 14 1/2 x 7 1/2 rectangle with eight oblong recesses, each of which is 4 1/2 x 2 1/2 --- all dimensions in inches. Later (1950s) usage by the wife's mother was to make individual cornbread muffins. Can anyone help?
