For the racer that is building a period correct cackle fest car or a bad ass street rod RBS has these two genuine Donovan used cast alum. valve cover breathers.
The version we have here are known as the tall which measures 3.875" tall from the mounting surface to the top of the breather. The breather uses two .312" fasteners on a 3.875" bolt spread and is machined at thirty degrees where it mounts to the valve cover.
Breather is made from cast alum. and could be polished to a high luster once again or run as is.
