This is Later....
....Than 1969. Sears/Roper used another cooktop stamping entirely in '69, plus they weren't using digital clocks that early. Their late-'60s self-cleaners used an electric latching system for the most part, rather than the manual latch shown here, and they didn't have black glass at the time. Even when they did get black glass, it was a glass panel over a solid oven door on most models, not an actual window. I can't tell from the photo if that's true for this example.
I'm thinking somewhere between 1974 and 1976 on this one. It is a very nice range, upper-MOL, with a good feature set, just not quite as old as thought.
