Thank you John,
As to your starter, it depends on which Anzani you have fitted to your car. I have the big Anzani and all of my electrics are CAV. In consideration of your head and sidelights and the CAV panel on your dashboard I would assume you have the big engine and CAV electrics???
I have just looked at my car and cannot see any numbers on the starter and I am afraid the spares list is not any more illuminating only listing it as '12799 Electric Starter CAV'. The number is of course an AC number as they numbered every part of the car!! I will dig a little further into my archive and see if I can find a model number.
All the best,
Tom
