To Wor.{Arthur Wormald - General Works Manager} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KT.15.11.33. With reference to Wor{Arthur Wormald - General Works Manager}7/R.14.11.33, we are running these Duo-tread tyres, but have not covered sufficient mileage to be able to pass a considered opinion on them. One disadvantage we have so far noticed is that they are noisy on smooth wet roads; on the other hand they are good non-skids. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
