Norge wasn't exactly a trend-setter with its designs, but even so, I doubt that's a '56. From the looks of the sole original handle on the cabinet door, I'd say it's closer to '46. Still, those look like kick-ass burners and I like the recessed lighting.
I think that beauty Hans owns with the adjustable light bar is closer to what a '56 Norge would look like.
I may not like Norge's washers, but their stoves and refrigerators are an entirely different matter.
