X4240 FIXING for Radiator. X4219 Replying to your Hsl/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 less 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} [STAMP] REC'D 15 DEC | ||
