Crankcase Breather (straight thru) - AF

This is modern replacement for the straight thru breather used on Norton crankcases and timing cases. (note: it is a breather - not the one-way pressure release valve also used on Norton engines, this is listed elsewhere). It has a slightly larger AF hex than original, however it is reasonably priced if you are not too concerned on originality, is a good quality item and is cadmium plated
