| DA.{Bernard Day - Chassis Design} FROM R.{Sir Henry Royce} (At Le CanadelHenry Royce's French residence.) C. to - BJ. BY.{R.W. Bailey - Chief Engineer} HS.{Lord Ernest Hives - Chair} ORIGINAL REC'D R8/M5.3.28. & DESPATCHED FROM WW. 8.3.28. X7340 "SS{S. Smith}" PROPELLER SHAFT. N. Sch. 2547. I prefer the pins going right across for fixing the tubular shaft to its ends. Avoid oil pumping by passages or holes to return oil or air past sliding serrations. I think we should keep to the square hole with rounded corners, like the original - as N. sch. 2547., not N. sch. 2550. R.{Sir Henry Royce} | ||
