One 8-Inch Element.....
....Is a giveaway that a range was BOL or lower MOL, at least for ranges from the later '60s on up. Earlier, even luxury ranges like GE's 30-inch Stratoliner of the late '50s, could have only a single 8-incher.
I personally do not like the arrangement; I prefer upper MOL or TOL ranges with two 8-inchers. You can saute on one, and boil up a big pot of water for pasta on another, that kind of thing. With only one big burner, you are much more limited if you really cook.
The other thing I don't like is that with only one big burner, it tends to wear out fairly quickly, since it's the most-used burner on the average person's range. Two big burners allow you to rotate usage between them, with the result that the two burners last longer than one burner and its replacement, at least in my experience.
