It might be an older Raytheon machine. The timer dial knob is the same shape as the one on our '97 washer, but the two smaller knobs are not. I don't know who made Amanas before Raytheon. Maybe Amana was still Amana up until the Raytheon period?
This was Amana's second panel version, first with back-opening lid, about mid-late 80's. Amana had never offered a laundry line until about 82. All Raytheon/Speed Queen perforated basket style.
Exact model that I have--Amana LW3303W, purchased October 1991.
Still going strong, with multiple uses daily. Over the years, replaced the motor twice; brake pads once; and pump once. That's what I call good service.
