| Mr Barrington. Sir H R ? O.O. admitted 21.8.12 RE STEEL CLUTCH RINGS We have now run these for some time on Experimental Cars and recommend same should be adopted as standard. We have run these on one car for 2500 miles, the clutch of which has had considerable use in hill climbing etc, and same has given every satisfaction( this car is on the Continent with Mr Johnson) The above report is also confirmed by cars which we have at the works with these rings fitted.
