| To RHC.{R. H. Coverley - Production Engineer} X4644 306 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}14/KW.15.9.34. SpectreCodename for Phantom III Brakes. We find a considerable amount of brake sponge on this car is due to deflection of the aluminium shoes. For test purposes therefore will you please put in hand similar shoes in cast-iron for the foot brakes, front and rear. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
