Early '50s, Indeed!
That's a 1950 model, an RM-35, I think. The model-year giveaway is the presence of the oven vent on the cooktop, between the left-hand burners. Frigidaire moved the vent to the backsplash the following year.
This is not a range that grows on trees, people! Someone hopefully will give it a home. P.S.: This is the "Deluxe"; the other 30-incher for that year didn't have the automatic oven control.
