Cox - Advertising Manager} RE: CONTINENTAL TOURING SALOON CHASSIS. Referring to DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}3/M.7.11.30. it is fairly certain that the cantilever support for the rear end of the battery was responsible for the complete failure of this battery in something like 17,000 miles i.e. in a few months instead of five or six years. The cause of the failure was excessive vibration of the battery, and since the only difference between Phantom ll earlier type and the one which gave trouble, was the use of the cantilever instead of the full cross member, there is little doubt but that the introduction of this cantilever was the actual cause of the trouble. In view of the foregoing therefore, I cannot agree that the cantilever support to the rear end is practicable. The cantilever design has been cancelled for N.2 series entirely. BY.{R.W.
