I think the notched handle started in 72 so yeah, it's the last of the breed.
Kenmore reached it's "pinnacle" between 1968-1972. With the metal door handle, the keyboard controls, and the perm press agitate-fill feature. After 73 the machines got the plastic tub ring and outer tub, the notched handle, the FUGLY control panels, the new 'tators (penta-swirl/vane) until they hit rock bottom with DD.
