Yep......... it could be a standard capacity model, and definitely, it's a late 1970's model (1976-79). With exception of the color, the amount of water level settings, and the placement of the bleach/softener dispenser, that machine looks EXACTLY like our 1978 large capacity model sud saver (the same amount of speeds and cycles, but only ours was white, it had four water levels instead of three, ours had a Penta-Swirl agitator and the fabric softener dispenser was mounted on top of the agitator).
