1948!
That's a '48 Frigidaire, one model off the TOL. It's the single-oven version; the TOL had double ovens. You can tell by the presence of only one oven vent (the round thingy on the backguard) and the presence of only two knobs on the backguard's control panel - the TOL RK-70 had three.
Also, by blowing up the photo, I could see that this range has the thinner, interwound elements, not the fat Radiantubes intro'd in '49. Frigidaire carried this design over into subsequent years, demoting it from TOL status, but those years have the Radiantubes we're all familiar with, not these elements.
P.S.: That's a rare piece of cookware sitting atop the range - it's Dansk Købenstyle, designed in '54 by Jens Quistgaard, in the most desirable color, turquoise. When I was collecting Dansk, I probably had twenty pieces of this stuff, in this color. Finally sold it off because it was too chip-prone to use much.
