Your Detroit range is a jewel!
Ranges from that era have always been a favorite of mine for their spectacular porcelain finishes. They came in a dizzying variety of colors and designs. They're also built like the proverbial "tank" and with just a little care like greasing the valves they seem to last forever. Do you do much baking? I bet the oven produces perfect results. Most of these old ones do. Back in the late 40's my mother had a Detroit Jewel similar to yours which she says was the best oven she ever used. She lived above a motel diner and baked all the bread and pies served there! I have a 1931 Magic Chef which has the best oven I've ever used for baking bread. There is a lot of heavy steel in these old ranges which gives a wonderfully even, radiant heat, and they hold the heat a long time after shutting off the gas!
