Roger,
It is a '58 Deluxe (RD-38-58). It's the second cheapest of 30" models that year as only one "Super" model remained for 1958, the one without control panel lighting or a clock/timer.
There were two 30" DeLuxe models that year, this one which replaced the previous year's nicer Super range and another one with more bright trim on the console, a surface unit pilot light, Heat Minder and Speed Heat burners and a gray porcelain oven liner instead of black.
