The early sprint, or what is often called the small headlight sprint, has a headlight unit common with a few cars. The 1st series Giulietta berlina for one. The late 1900 Zagato and the lightweight sprint are the same except the headlight rim is aluminum. For a long time the bucket was no where to be found. One of the vendors at the Jumbles in Italy has had a repro recently. The glass lens with the large Carello across the face (referred to as 150mm although measures more like 6 inches due to the curve, also called to as the 6 in. light) shows up from time to time at the Jumbles as well. The chrome (over brass) rim with the Carello lettering, the same story. There is a repro of the aluminum rim out there, so/so quality. The keeper arrangement which holds the light to the bucket is hard to find as well. I do not know of a supplier that has the whole kit from proper Carello parts. Be careful when looking, some suppliers are happy to sell you something close that won't be right for the car.
