| 312. W/N. from Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler} c. Mx.{John H Maddocks - Chief Proving Officer} c. GWH.{George W. Hancock - Head Chateauroux} Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}7/MH.{M. Huckerby}26.4.38. P.III CLUTCH. Next time you receive a complaint of judder which necessitates dismantling the clutch, will you please fit a set of the lighter clutch springs G.85734 Yellow if packing ring is fitted, or G.85733 Red if no packing ring. Our reason for trying this is because, with the present procedure of fitting a new plate it appears reasonable to suppose that the trouble may recur after another few thousand miles.
