I remember a Roper with the staggered burner arrangement you mentioned, Tom. A friend of mine that ran a group home/assisted living home had a 6 burner model in the kitchen. A couple of the valves for the burners were non-functional and one of the grates was broken, but when clean, it was a beautiful range.
The pictured Tappan looks very nice as well, probably a 40" model though so it may be just a hair too large for your kitchen, Ralph.
