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.
The rad. was bought as a working part some 20 years ago. It was never been fitted ot tested so condition unknown. There is no thermostat fitting. Good chrome to the mesh.
From car #3 (4325) when restored by Peter Giddings in 1971 , wooden strengthening fillets, pressed, and bolted into the front dumb irons (I have the original one which has a delightful French 3 inscribed upon it - perhaps by Bugatti himself?”
