I endeavoured to arrange that this could be fitted without scrapping axle which had suitable features forged on, but I believe it was chiefly condemned by Derby because of road clearance, and on account of complication and ultimate rattle by me. The road clearance is not important because even if damaged it would not be serious, and it is not in a dangerous place, and not as low as the brake drums. I am somewhat surprised that so little seems to be actually done to demonstrate the possible combination of the material, springs, dampers, and various RR. and other chassis which should be available at the Works - EAC. Northcliffe, etc. I thought much might be done with tyres and dampers, centre of gravity etc. Also careful comparison of other large cars - Daimlers, Renaults, Hispanos - none of which seem to have been driven from the simple and practical front axle scheme.
