| To RHC.{R. H. Coverley - Production Engineer} x206 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}2/KW. 8.2.34. Direct Braking to all four Wheels fitted to 3-B-IV. ------------------------- When the Drawing Office issued instructions for this experiment they forgot to issue details of the modified lever length in the brake differentials. These should be exactly as shown on N.Scheme 3879. We should be glad if you would urge in particular the levers for the front ropes, of 1.645" centres, as at the moment we have far too much front braking. Hs{Lord Ernest Hives - Chair}/H.Grylls. | ||
