UK Ford Cortina Mk1 for certain, that would be 62-66. Similar to the Elan switch and from my old notes on that I have a reference to the complete switch as Delco 68414, but I can't remember where I got that from.
Other possible Ford models would be the Anglia 105E, Cortina Mk2 and maybe the Escort Mk1 for the plastic knob itself. All about that period 62-68 and so likely candidates for Colin's Parts Bin raids !
