| 86051 To Roy.{Sir Henry Royce} c. to G/Mt. Hs{Lord Ernest Hives - Chair}/Wst.4/JH. 21.2.36. A.T. Speedometer with Increased Damping. Will you please arrange for the return of this instrument as we have now finished with it. It was submitted to us as a standard Bentley instrument, which had been modified with a view to obtaining greater damping of the needle. Car tests shew that there is little, if any at all, difference between this and our present standard instrument, certainly not sufficient to justify a change. Hs{Lord Ernest Hives - Chair}/Wst. | ||
