Those GE ranges are a favorite of mine, too... great mid century modern design at its best! I think they came out in 1957, with a stamped aluminum dash and the "old" clock dial (the pink is an early one like this), a year or two later followed with a glass clock and timer face, then updated to a full glass control panel (like the yellow one, probably a 1960 or 61). I think the following year was about the last of that dash, it had the full glass dash panel but with brown in the glass. I way more often see these in 40" ranges than in these more easily placed (in a modern kitchen) 30" models.
