From the age of 14 I was involved in the restauration of a Mercedes 320 - 340 1938 with a streamline bodywork, Stromlinieninnenlenker in German.
Not being too sure how to do, I managed to destroy the radiator cap and attached star, the symbol of Mercedes. It was made in zinc alloy and not as resistant as I by that time thougth it should be!.
However a couple of years later I made up a new one in brass by a number of hours of turning, milling and soldering.
