Norton 750 850 Commando Alloy Master Cylinder Cap 06-1920 Triumph Carburetor Definitely a step above theNorton's part number for this cap is 06 1920 or 06 4973. It should fit all Norton front disc brake master cylinders through 1973, I believe. It has been unavailable for YEARS, superseded to a garish plastic version that doesn't fit very well. This cap fits flawlessly and is highly polished. Stainless versions are also available.
