Thanks James. I remember they came both with the control portion vertical and slanted, like those in the brochure. I was pretty sure I had seen them that just said "Whirlpool" and not "RCA Whirlpool". Seems like they offered a pretty good value generally, even with the lower end models.
Someone a few doors down from my Grandma bought the "Supreme" set in this brochure in avocado green, as an upgrade to her RCA Whirlpool wringer washer.
I didn't know about the woodgrain ones until years later-btw Kevin, Kitchenaid seems to have come out with a "new" blue shade very similar to the appliance color of that time, so maybe its turn is coming around again. I kind of wish colored large appliances would take hold again. A few places have offered laundry equipment, which is nice.
Autowasherfreak-I did see a "locking timer" RCA Whirlpool once-one of the gentlemen out east has one. It was probably from the early 60s, a vertical partial console. The timer dial was in the center and there were black cycle and option buttons stacked vertically on both sides. The matching dryer had a windowed door, another cool thing I didn't realize they had offered til much later.
