PHANTOM II - FOOT BRAKES. ------------------------- With reference to standardisation sheet X.7370 dated 26.9.31. in connection with the incorporation of balls between the cams on the servo operating levers, although an angle of 45° is quoted, and is the angle used on LH.{Mr Haworth} Phantom II, Chassis 25-EX, the cam faces on R.H. Phantom II are 35°. Will you please let us know if we are to still have different angles for the two types of chassis or can they both be made the same, in which case should the angle be 35°.
