On the left is the factory original 1952 headlight knob (on the right is an old radio knob I'm using for a PWM LED driver / dimmer control)
So I believe that the knobs you show are same as factory for at least some years. The wiper knob was either chrome or red-ish plastic

Does anyone know the significance of the red centers? Is it just because plastic was the cool thing back in that era?
