Bradford was the house brand of Grant's department store. They were a mid-west chain, which went out of business in the 70s.
When I was a kid in Michigan, our neighbor's Dad was a Grant's store manager. All their non-builder supplied appliances were Bradford. Naturally the ones I remember best were the washer/dryer, which were Avocado, were brand new, and appeard to be Norge built, at least the washer. This was the mid-1970s.
This dryer appears about 20-years older? Who knows what manufacturer they came from back then.
