KitchenAid Medallion and Start Switch
It's true, the KitchenAid medallion is missing, the owners must have unfortunately removed it to update the look of the machine at some point. On the KDC-14 models, the start switch was just above the door handle. You can see the little chrome switch on the picture. On the 12 and earlier machines, they were on the side bar with a light. The side bars were under the door on the KDC14. (Interesting, but Hobart must have been superstitious, no 13 series.)
