| A.F.M. 400b. To. Rm.{William Robotham - Chief Engineer} CHATEAUROUX.I./.23.10.38. 8.B.V.- BENTLEY III. You will note from the Daily Report that the centre bolt of the N.S.R. road spring broke yesterday. This allowed the top inter-leaf to work out endways. We have replaced it, but it is somewhat damaged at one end. We made a new centre bolt from a K bolt and distance piece. The new front bump buffers feel very little softer than those removed. I understand they are 55 durometer but that 45 is really required. We have removed the I° wedges with a somewhat unexpected result - the car is now most noticeably easier to keep straight, and such small reactions as existed have been considerably reduced. We cannot immediately accept that this is due to the reduction of caster angle alone without further test and, therefore, look forward to trying the new yokes. The general improvement in the steering is, however, such that the drivers immediately commented upon it, nor have any troubles, such as reduced stability under braking been introduced. ---------- Rm{William Robotham - Chief Engineer}/IMW.{Ivan M.
