Frigidaire introduced its line of electric ranges in 1937. Before 37, they made only refrigerators and electric water heaters. By 1941, as Greg dated it, this range featured a great improvement. Frigidaire had replaced the almost solid elements with the tubular elements and 5 heat switches. A long time ago on American Movie Classics, I half watched a movie where a young couple were in a small home with this stove in the kitchen. In looking through my files, I found two interesting Frigidaire ranges, the BC-5 and BC-6 offered starting in October 1939. They were combination ranges. Model BC-5 designed for use with wood, soft coal and other solid fuels. BC-6 used Anthacite only (Hello Phoebe Snow). Water backs and coils available on both models. These two devices enabled houses with coal or wood stoves to have a central source of hot water before gas, oil and electric storage tank water heaters were widely used. The cooktop had (2) 8 inch elements at 2000 and 1200 watts and (2) 6 inch elements at 1200 watts. Over the firebox, there was a cast iron plate with two "eyes." The stove had an all porcelain oven with a 2000 watt bake element and a 2700 watt broil element. Both ranges were 38 inches wide, 36 inches high and 32 inches deep.
I saw in my 1941 files that Westinghouse introduced the Laundromat that year. I had forgotten that it was available in 1941. Blackstone was not the only automatic going up against the Bendix Automatic Home Laundry before the war.
