| To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to CJ. c. to E.{Mr Elliott - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} [Handwritten Annotations]: (Hatched in red) illegible, k-c, -sc, IIB, N, A, X4219, X4247 [Stamp]: ORIGINAL BOX "GOSHAWK 11" - ENGINE AND GEAR/UNITS. Hsl/LG22.7.21. We have had the above engine running on the Test Bench. The first impression of the engine running is very pleasing. The valve mechanism appears to be very quiet. So far we have had very little load on the engine; it has simply been run light. The testing of this engine will be carried out during the time the works are closed for the holidays so by the time the holidays are over, we hope to have a considerable amount of information with reference to this engine.
