For those of you with mid-century houses or habits, I offer this Roper with Spectro-Matic burner control. I became aware of this when a reader contacted me wondering what the S on one knob meant. To tell the truth, I’m still not sure, though I’m fairly certain it’s the broiler knob. But check out those color-coded knobs!

It’s interesting that Roper decided to highlight the simmer feature with this model because as far as I know, all Roper burners from this era and earlier have a center-simmer feature, when the inside ring of fire stays lit while the outside one extinguishes.
The brochure in this gallery was sighted at eBay, and the stove pics are from the reader in Westchester, Illinois.
Also springing from this era is the Roper Space-Master.
