| OY. From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} x7840. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}8/MJ.4.6.30. We think that there has been some error in the wheel and tyre weight which you have been given because the weight figure for our 20" wheel and tyre comes out at 136 lbs. pair. Otherwise, we think that these figures are reasonable. We should like to point out that we hope to reduce the road spring weight as time goes on.
