Radiator made by Grenier-Mercier (GM) of Avenue de Bouvines 8 - Paris for a small single or 2 cylinder De Dion of circa 1909. Surround needs small repairs but is in quite good condition for its age. The core will need to be replaced.
NOS Bugatti radiator cap , very old but in good condition. I believe this was made in USA as it is from a box of parts bought from an American racing friend
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..
