| RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} P.Z. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}9/W.2.1.33. 3 Per.II Brakes for France. We do not wish to run the larger servo in France as we gain no advantage from it and it is very noisy. Will you please therefore fit the original type servo with the modifications shown on the attached print to keep oil from the fabrics and also the original 2/16 servo gears. We should also like 35° cam fitting. These require making. Will you also please make two front equaliser levers to the ropes of 1.475 centres and a sheet lever for the rear equaliser of 2.625 centres. These will be fitted in France if the servo hits its stops too easily. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
