It is important that we should have an honest comparison between the vibration of our engine and other six-cylinder engines of similar power. I understand that Mr Platford is to have an opportunity of trying a 6-cylinder Daimler; - if he can try this Wolseley also, the comparison will be very useful. The Autocar report states that the vibration difficulties have been overcome by balance and design and without the use of damping devices; I suggest that it is possible that this [Footer, upside down] R.R. 235A (100M) (W) 527. 26.5.11) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1695 | ||
