| X3984 To BY.{R.W. 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} Ha3/M.19.8.22. RE. IMPROVED 40/50 X.4545 Y3984 Please receive N.Sch.1316 shewing the modification to the frame required in the first move. This enables us to use front wheel brakes and radius rods with the existing engine, and also to use the new engine with the existing gearbox, back axle, spring system etc. so that we expect that this frame will also cover the 2nd. move. The object of sending you this drawing is to enable you to make enquiries with a view to ordering these frames and to let us have any comments which you may wish to make at this stage.
