| COPY X.4257 R7/G30. 12. 20. To D.A. from R.{Sir Henry Royce} Copy to C.J. RFC. X3558. RE "GOSHAWK" BRAKE GEAR. X4287. With reference to your memo DA{Bernard Day - Chassis Design}2/CB20. 12. 20 regarding the above, we want to make this as perfect as possible so as to compare with "Goshawk II" as we may decide that the gear box and back axle, control and "Goshawk" I is superior and well worth the extra cost over simpler scheme on "Goshawk" II or we may decide that "Goshawk II scheme beats Goshawk I and therefore best for new model of large chassis.
