ORIGINAL D I R5/G23/2/21.1921 RECEIVED With reference to the clutch for "Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II", we believe that an error has arisen that the pressure plate was to be made of wrought steel drop forging instead of a cast- ing of iron, semi-steel, brass, bronze, or aluminium-bronze, using the least costly material which is found to give satis- faction.
