| ORIGINAL BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} C. to S. HS.{Lord Ernest Hives - Chair} (12) 217 n J.{Mr Johnson W.M.} 4. GEARBOX. DA{Bernard Day - Chassis Design}2/M20.7.31. Y5310. On Sat. last we despatched to you N. scheme 3314. shewing the gearbox rear suspension, backing light switch attachment, etc, etc. It will be noticed that there is a slight modification to the universal joint, and to the length of the 3rd. motion shaft. There is a suggested method of making the pendulum lever. We should be glad to know whether you consider it would be of any advantage to make the lever and shaft in separate pieces pressed together instead of solid as now.
