Jim, our neighbor had to replace her 33" LK gas combo in due to a hole being burned into a major component with another gas LK combo in like late 1964 or sometime in 1965. Instead of the buttons having a silver/metallic facia appearance, they were white and had wisps of various pastel colors under the cycle word lettering. All the same descriptions for cycles on the buttons until the last version, which changed the Super Wash to an Enzyme Soak. That same Enzyme Soak timer was used for the Wrinkle Guard feature with its periodic tumbling.
