| Rudy type out & distribute. ORIGINAL 9/28 Accident. turned note HS.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} LHS{Lord Herbert Scott} E.{Mr Elliott - Chief Engineer} BJX, PM, CWB, C, Sq, Nor. Unsprung weight upon which turns the force of lateral momentum I cannot see how the steering could be wrong & right again it is just possible to have a seizure or a brake come on. but it is so remote as to be unbelievable. my impression is that the back wheels slipped & skidded. (1) wet road (2) a cambered road. (quicker sideways) (3) worn tyres. (4) large dia tyres for the load. (5) foot pedal / accelerating from 50 up to ? (6) powerful engine for the load on back wheels. (7) Tyre pressure may have been low I hear Hispano. do not fit large tyres to their axles on the sports. model. PTO R | ||
