That's about a 1968 or so Sears top-load d/w, I grew up with the front-load version. Turquoise racks, in the top-load the Roto-Rack is split and hangs off a center support. Stainless spray arm, black plastic spray tube. Doubt there was a rinse agent dispenser, a small flipper detergent dispenser with a lid (fill one side, twist and dump, fill other side, flip down the lid)
