Official name was Alfa Romeo 1600 Spider and not "Duetto". Alfa Romeo never ever used anything but 1600 Spider. Head light cowles by Perflex. Popular design like Ferrari and Jaguar E-type. Alfa continued until the mid '70s with this arrangement in Europe. The 1750 Veloce had the same cowls in Europe.
The Duetto was also nick-named "boat-tail" and "Osso di Seppia", which means "cuttle-fish-bone". Here is a leaflet of the Duetto in PDF.
