The somewhat doubtful arguments in favour of the above will not apply to J. {Mr Johnson W.M.} 3. except cheapness, (and even this can't be much when Austin gives aluminium.) I fear the weight in many ways. We in England do not keep castings down to weight, but like drop forg- ings they grow heavier. I certainly would not add to our reputation unless it were decidedly better in performance and repairs. (A bad bore means nearly a new engine.) Weight in this position is bad for steering and pitching. We must not lower our chances of sales. Person- ally I would not buy a first class car with a heavy engine. The matter will be carefully considered. R. {Sir Henry Royce} | ||
