| To By 617 ? Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}2/JH.22.5.37. Spring Drive - Wraith. The drawings of the crankshaft damper flywheels for Wraith do not show the usual oil drain holes. Such a damper that has run on 6-B-IV is full of sludge. Will you therefore please alter the drawings to show holes exactly as on the production Bentley spring drive. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
