Please find the following sheets herewith, passed by R.{Sir Henry Royce} DA.{Bernard Day - Chassis Design} and E.{Mr Elliott - Chief Engineer} for chassis work, and R.{Sir Henry Royce} and E.{Mr Elliott - Chief Engineer} for aero work:- PHANTOM 2. FIXING FRICTION SURFACES OF CLUTCH ON DRIVEN MEMBER. R.{Sir Henry Royce} remarks "Agreed, but is the plate carrying the fabric as "thin or as light as possible. I have suggested duralumin. "I understand that with this we are using cast ironsurfaces "to rub on fabric." FRONT BRAKE LINERS .375" THICK. R.{Sir Henry Royce} remarks "Agreed - would our staple system of fixing be better "or less costly for fixing liners"? E.{Mr Elliott - Chief Engineer} remarks "Agreed - does this not also apply to the back brake "liners"? REVERT TO 4 VENTILATING PANELS IN BONNET. STRAIGHT BATTERY SERIES CONNECTING LINK. 'H' ENGINE.
