Neat Range
I'm not sure that the front units look like the first Radiantubes. They look like later units, possibly generic units of the Corox design. I have a range with the first of the thin Radiantubes and these lack the distinct loops at 11 o'clock on the outside and at 1 o'clock on the inside of the units. In the 50s, many of the manufacturers of surface units made replacement kits so that Calrod elements, for example, could be installed on any brand of electric range. I think Chromalox was the last to offer that. I used those to replace the front Radiantubes on the 1954 RT38 for some speed.
Huntsville and surrounding areas would be a good place for electric ranges, just like the Pacific Northwest. With the coming of TVA power, many homes went from solid fuel ranges to electric. A friend who grew up in Huntsville told me that before they got an electric refrigerator they could only have Jello in the winter when it was cold enough outside to make it set up. The rest of the year, the icebox did not get cold enough.
