The King of Gas Ranges
Only about 1000 of these were built by O&M between 1949 and 1952 or 53. They cost around $675 when new and were sold as the "Aristocrat" ('estate' as used in the ad was mostly a term describing it's size as most ranges of this size were for very large homes - estates)
Beautiful if you have the budget and 57" of space for it. I think the CL range might be a bit high, a fully restored range can sell for the prices she's stated so it would be interesting to see a list of her husband's restoration process.
O&M had some of the prettiest gas ranges of them all but we see very, very few around here.
