Hs{Lord Ernest Hives - Chair}12/B34114. With reference to heat treatment of the Front Pivots. I am agreed that the temperatures 800°C and 540°C are probably good and safe ones. I am also pleased that our heat treatment generally turns out to be more regular and consistent than that we get from outside. R.{Sir Henry Royce} (Handwritten in left margin: 82/x) | ||
