INITIAL | DATE | REMARKS
SG.{Arthur F. Sidgreaves - MD} | 13.5.31. | Agreed Sg.{Arthur F. Sidgreaves - MD}
R.{Sir Henry Royce} | 18/1/31 | Agree W.R. Personally I do not think this scheme worth while.
WOR.{Arthur Wormald - General Works Manager} | 19.2.31 | Agreed Wor.{Arthur Wormald - General Works Manager} In discussion, I cannot see exactly how it serves the dynamo.
C. | 14.1.31. | Agreed C. It does not appear sufficiently to make any practical difference.
RG.{Mr Rowledge} | 14.1.31. | Agreed Rg.{Mr Rowledge} also have on Mr. report on my suggestion of the possibility of
DA.{Bernard Day - Chassis Design} | 15.1.31. | Agreed Da.{Bernard Day - Chassis Design} maintaining the rate of charge with speed by using another
BY.{R.W. Bailey - Chief Engineer} | 13.1.31. | Agreed By.{R.W. Bailey - Chief Engineer} problem of which, probably there is advantage in my suggestion
EP.{G. Eric Platford - Chief Quality Engineer} | 16.1.31. | Agreed EP.{G. Eric Platford - Chief Quality Engineer} Should like road test before agreeing.
