Not Gambles
I've never seen anything but Coronado branded appliances from Gambles' ads, service info, etc. That was their house brand for many, many years. There was a Gambles store in West Point, NE next door to the Safeway where my grandmother did her shopping. When I was old enough to be trusted alone, I would go to Gambles while she shopped next door. Many times I was shooed out of the appliance department. I was so enthralled with the Franklin angel wing agitators and giant looking tubs compared with my grandmother's standard cap. Maytag and our GE at home.
Gambles started carrying Norge built laundry machines in the early 80's, just before their exit from most markets.
