I wonder if they have the knobs? That is a very heavy stove and wider than most combination fuel cookers with 4 "eyes" for both fuels, like close to 60", maybe. I wonder if the oven has a thermostat for when it's heated with gas and the thermometer is for when it is heated with wood. My mother grew up cooking on a coal range in the winter and on kerosene in the summer, but summers were short in Hibbing. They had to start all of the seeds for the garden inside and then set the plants out after the last frost.
