Don't know about the gas range,
But the Pink GE 40" is a very unusual model. I've never seen one(of this style GE) where the clock is mounted above the rest of the backspash. 1957 was the first year for this style cabinet, and the round clock was used that year (usually set into the backsplash), and then '58 and after had rectangular clocks set into backsplash. I wonder if they used the round clocks later in this type application?
The upswept cooktop with the burners at opposite sides, rather than on the left, is also quite rare. My cousin Mary had a double oven model with the upswept cooktop, but the clock (rectangular) was in the backsplash, and the burners all on the left. The outlets were also grounded. Her daughter bought it for her in '63 or '64. Hope someone gets this, though the price is kind of high for having a large chip in the top.
