I have for sale an original bonnet for a single cylinder De Dion Bouton.As you can see it needs a little work as its missing the front hatch and top cover but they shouldn't be too difficult to make.If you are interested I will send you some more pictures.I am located in London.
Broken down. Not working. Could bake a working engine from the 2. Found in grandfathers / uncles garage along with large amount of other de Dion parts..
