I saw a Roper range w/ the burner knobs back there behind the burners like that, once--and the thing was a double-oven, so the 2nd oven was an UPPER, right over all that!
I would check to make sure it has top heat for bake. When Kelvinator/Gibson made ranges for WP, there were some with no top heat during bake, but don't know if that was from Kelvinator or elsewhere on the family tree.
