Just fyi these are great ranges...
and imo this early to mid-late '50s period produced some of the best build-quality ranges, better porcelain, heavier gauge steel &c. My mid-70s FD 30" rnage is not quite the same construction quality but still a pleasure to cook or bake with. FD was a cut above most ranges until about 1980 when sold to WCI. Be aware the Frigidaire RadianTube burner coils tend to heat up and cool down somewhat slower than thinner coils such as GE Calrod, but you'll quickly adapt, and they do put out prodigious heat once they get going! No self-cleaning of course, that didn't come along until the mid-60s, I'm sure PhilR will know the exact year. Good Luck and hope you can be it's new owner!
