| To RHC.{R. H. Coverley - Production Engineer} X1110 Hs{Lord Ernest Hives - Chair}/Smth.1/KW.23.1.36. Borg & Beck Driven Plates for Ph.III. There are 2 of these in the shop waiting to be fitted to cars. Will you please measure for us the amount of "run out" on these discs, that is, measure the maximum out of flatness due to both the waviness and saucer-shape of the plates with the hubs mounted on a mandrel. Will you also please measure the cushioning. Since we are instructing these plates for the first 12 production chassis we should like these figures without delay, so that we can take the matter up with Borg and Beck if they are excessive.
