X.4219 X.4240 Replying to your Hs{Lord Ernest Hives - Chair}1/LG7.12.21., I am pleased that the breakages are consistent, and am not proposing to alter the radiator fixing; it would be wrong to stiffen these, as they might break sooner, or damage the radiator. The flexibility which has cracked them was intentional; we must use plastic metal, and try if road experience demands any more expensive scheme. I am so pleased with the scheme of fixing this radiator that I am slow to abandon it. R.{Sir Henry Royce} | ||
