Colloquially known as the Chambers Model "D"
officially it was the "M-9H" or some such... made after Chambers was sold to RangeAire around 1958... we had this exact range, but with gas burners, a few years ago, typical Chambers quality, weighs over 500 lbs... you really need 4 people to move one! This electric version is seldom seen.
We got rid of it and use the '58 GE at home now, but an Electric Chambers "In-A-Wall" oven at camp, with a Chambers 27" propane gas cooktop, as the electricity goes out on a fairly regular basis there!
