| To Hs.{Lord Ernest Hives - Chair} from BJ. S E C R E T. RE. INDIA. BJ7/H29.6.25. With reference to the two secret cars you brought down last week, to be tried by H.{Arthur M. Hanbury - Head Complaints}, CWB, and BJ., we found the new strong springs necessary for front wheel brakes were satisfactory, although one obtains considerably harsher vibrations over some kinds of roads than with the standard springs. We should prefer 20% stronger rather than 25% stronger, if you consider this would lessen the vibrations and at the same time be strong enough. B.J. C O P Y. | ||
