Brass fuel filter. It's missing a screen, otherwise, it is OK.
It is marked "Harford Petrol Filter H.H. Ltd." I believe it's British made.
I can send more photos and I accept PayPal.
I offer here an original fuel pump for Horch and Mercedes. It has NO cracks and is newly sealed including a new membrane, it is fully functional.
Very nice condition.
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..
