| -2- a view to discovering whether they are really useful with the new engine and with our rigid body construction. They give trouble through grunting on rough roads, like a siezed shackle, and with our stiff bodies, we do not find any appreciable difference in noise or rattle whether they are connected or not, even with existing engine which is much less rigid than the new one. 5. Whoever comes should be closely in touch with developments of the new suspension, the use of hypoid gears etc. He will probably want to visit Gleasons. 6. It would be better if he were conversant with the Derby riding-quality tests and were able to tell us whether there is actually an important difference between their riding-quality problems and ours, due to road differences, etc. Any possible changes we may have to make in the R.R. hydraulic dampers such as the use of zero-test oil, might well be done while he is here.
