Bailey - Chief Engineer} from Da.{Bernard Day - Chassis Design} c. to CJ. c. to Wor.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} X3548 81 HERON FOUR WHEEL BRAKES X.4850. Please receive N.sch.1351 shewing the hand brake operating gear and some preliminary information regarding the Servo Motor. Further information regarding the latter will be sent on at a later drawing, but this one will enable you to deal with the ratchet mechanism and the lower part of the hand brake gear. It will be seen that the hand brake lever is the Goshawk piece exactly, the forging comprising the bottom bush alone being altered. The precise angle of the hand brake lever is not yet.definitely fixed. Da.{Bernard Day - Chassis Design} | ||
