I have brochures for U.S. Speed Queen from the early-mid 70's that offer a full-line of appliances. The ranges were Modern Maid, dishwashers were D&M and refrigerators look to be WCI-Admiral. They even had disposers (Whirl-a-way) and IIRC, a hot water dispenser.
I also have another SQ brochure from about 1936 for refrigerators. I have no idea who might have made them for SQ if they didn't, but they look like very nice units for their time.
