| ORIGINAL. TO BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}1/M18.11.22. c. to GJ c. to HGR. c. to HS.{Lord Ernest Hives - Chair} ✓ HERON FOUR WHEEL BRAKES. V4550 Please receive N.sch. 1351 showing the hand brake operating gear and some preliminary information regarding the Servo motor. Further information regarding the latter will be sent on a later drawing, but this one will enable you to deal with the ratchet mechanism and the lower part of the hand brake lever 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} [STAMP] RECEIVED Hs{Lord Ernest Hives - Chair} NOV 21 1922 [STAMP] | ||
