1920's FIAT Le Nivex fuel gauge, I think it's for a 521. It has a bevelled glass and still has its proper zero-needle setting screw.It's a little dirty, and would benefit from a clean-up.I can send more photos on request.I accept PayPal and can post overseas.
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..
