| Rim 7326 To Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} By.{R.W. Bailey - Chief Engineer} Bn.{W.O. Bentley / Mr Barrington} Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} Bs.{A J. Barnes - Assistant Manager} re Bentley Tool Kit. Referring to your memo Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux}9/KW.5.3.35, it is noted that the proposed saving on the tool kit amounts to 3 lbs 12 ozs. on a total of 31 lbs, and this is equivalent to 12%. We recollect that when we first made the wheel spanner for the Bentley it was of the unribbed lighter type like the one you propose to use, and was condemned by the Experimental department as it would not stand up to the use of the mallet or hammer. The hammer also was one arrived at by experiment to be a weight suitable for dealing with the Rudge Whitworth type of hub. It is true that since then the manufacture of the wheels has been improved and we have better fitting hubs in consequence. We would, however, draw special attention to the testing of these parts, which could be done in connection with 5-B-IV which has gone to France fitted with this kit.
