Hey VC... All Model 4 Automatics that Im aware of were wire cord starters,and the first Model to use this starter type,so 1957. It was replaced by the rope/cord style on the Model 5 S1 and then was reintroduced later in the series. The ends of the wire have a ball and it threads into the handle in the Image and the 2 halves are then joined and the Green or black Rubber boot goes over the knob.. The starter in the Image is also a wire cord starter,just the next version(This is the one your enquiring about)
Ill get some pics of all 3 recoil starters when I can so you can see the differences.
