Referring to RHC{R. H. Coverley - Production Engineer}/SB.{Mr Bull/Mr Bannister}1/FH.28.8.37, kindly note we are arranging for the hub serrations for the Bentley III, 2A, and Bentley 'M' series and Wraith, to be the same in order that one broach may be used for all types. In regard to the axle shaft serrations, Bentley 2A. Bentley III, and Wraith are being made identical, but we are not proposing to alter the 25/30 HP. as this will be replaced by Wraith. BY/Mtn. | ||
