Brings back memories. My grandfather had a range with a plug in area and that was the plug used to plug in the percolator. More recently, as an Innkeeper, the inn kitchen had an avocado green GE double oven range and it was a workhorse. Loved the convenience of the smaller side oven and the space on top to put things on straight out of the oven. It had push button keys for the burners. Don't know what vintage it was and we are (thankfully!) no longer Innkeepers.
