| To: [Redacted] Copy to: [Redacted] Hr/Rm. {William Robotham - Chief Engineer} ------------ 612 R {Sir Henry Royce} /HDY. {William Hardy} /MN.13.7.36. ------------ Wraith II. Clutch Casing. We send herewith W.Sch.4853 which shows the above. This casing is similar to that for the 25/30. The principal differences are the reduced diameter of flange for the gearbox, the absence of a front brake equalising shaft and attachment of the front brake dashpot to the clutch casing. With regard to the clutch operation this is shown by L&C's 5147 and 5148 but the shape of the external operating lever should be as we show on this scheme.
