Sue,
That is what was called by "Griswold" and Angus Broiler. One is shown in a 1974 catalog sheet I have and that's during the period that General Housewares Corp owned both Griswold and Wagner with production of all products in the Wagner foundry. The broiler is based on a Griswold style pattern but I am not aware of Griswold having made such a pan when in Erie, PA.
These stovetop broilers work very well for steaks, chops, chicken, fish, or whatever. No jello please. Originally designed c.1930 by Alan Axford who died in 1989 at 91 years old and lived about 5 miles from me. His Axford foundry was the Mission Foundry and Stove Works in San Francisco. I've never been clear whether they made some of the "Axford Broilers" (in three sizes) or if they parceled out all or some production to Lodge (they did) and Wagner (later production). Early Axford Broilers are marked Pat. Pend. on the handle. Later ones Pat. 1931. Later ones marked Broil-Rite Broiler on bottome. Also, the later pans including many 1931 dated ones have an opposite side handle to aid in picking up these heavy pans. No opposite side handle on the Axford Jr. pans which are about a size 6-1/2. The very large Axford Broiler is very rare and I've seen only one that was marked.
Directions for use: "Place pan on stove top and get it VERY HOT. USE NO GREASE. Put meat in pan and reduce flame. If pan smokes excessively, flame is TOO HIGH. Do not cover meat. Chicken may be covered after searing on both sides."
A cover was made for the standard or 11" size of the Axford Broiler to turn the pan into a double skillet type of pan. A cover was also made for the Jr. pan but it is not highly marked as is the standard cover.
I'd suggest you go for a nice, older Axford but the "Griswold" one should make food taste just the same and, actually, it is a nice casting too. You didn't really want to know all this, did you?
