| BY.{R.W. Bailey - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Y401. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}2/WJ.22.2.30. 28820 Since we have been able to increase the number of balance weights on the 20HP. car, we think we should do the same thing on the 40/50 as this will enable us to accept tyres for a bigger car to the same standard as we insisted on for the 20 HP. i.e. 67 ins.ozs. out of balance. The additional balance weight will also be useful in correcting tyres which wear out of balance more than the specified amount. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
