To clarify the differences, the 60s/70s levers were steel under those rubber covers. The knob side was 3-piece, plastic wing nut w/ brass nut connected to a round steel knob which is held in place by a pressure spring.
The 50s levers use the funky steel knob w/ Frankensteinish bolts. The rear 50s lever and cover are slightly larger than the 60s model and the axles are all chrome. Scott still in St.Paul
