| X.3175. To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to BJ. BY.{R.W. Bailey - Chief Engineer} R3/M7. 6. 26. JACK ON 7-EX. The jack on this car does not shorten enough to go under the front axle for the medium pressure tyres. I find it too short even on garage pavement, and no doubt it would be worse under unfavourable conditions on the road. R.{Sir Henry Royce} | ||
