I've Always Thought....
....This was an interesting 40-inch range model for GE.
It's a P*7 model that was not TOL. It had two ovens, as well as the desirable two large/two small burner configuration.
But it did not have Sensi-Temp, the meat thermometer, the griddle or the rotisserie. A good "workhorse" choice with good features, but without the frills.
I don't know the model number for '64, but the next year, it got a slightly different clock/timer unit and was Model J 439.
