The "Special" cycle used to have slow agitation and fast spin. Slow agitation to prevent damage to the fibers and fast spin to remove the water that wool holds. That was why the "G" program for woolens was in the orange Normal cycle of the 1958 LK. The spin speed was in the cycle in the timer, but the agitation speed was set independently and the Normal cycle was the only one of the three that provided the nigh spin speed. It also gave a warm rinse as did older GE programmed washers so that the change in water temperature would not cause the wool to draw up and shrink from temperature shock.
That machine probably dates from the 80s. A very similar one was in the home a friend bought new in Vero Beach in about 1985.
Wood grain on control panels: When that was put on stoves, John called them "wood stoves."
