My Aunt had that exact range in her house, it was called a GE Mark 27 drop in with the P7 automatic oven cleaning. It was 27" wide and it sat on a short base cabinet, hers had a drawer in the cabinet. Her house was built in 1966 and this was the range her builder gave her. In the mid 80's the self cleaning stopped working and she had to replace it, she replaced it with another GE 27" drop in which now was called a Spacemaker. The new range was almond and had the burner knobs in the front, 2 on the left side, 2 on the right, the original range had the push buttons across the back. She did a lot of cooking on those ranges, amazing only 1 large burner and they were a family of 6.
