| Conference To Rm.{William Robotham - Chief Engineer} 8.2.37. WRAITH ECONOMIES. Small eye for front end of rear spring. This will make it impossible to fit rubber shackles. Saving in cost per chassis 13/- Rear springs with top plate only cadmium plated, rest of spring finished to standard of Humber. Simplified lubrication for the top five plates. WOODHEAD. Saving per chassis at least £3. 0. 0. Deletion of needle bearings from front suspension. Bearings for top triangles to be bronze. Bearing for lower trianglesto be silent blocs. Saving per chassis at least £2. 0. 0. ----------- Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie} 2nd. Wraith Electrical System. Our immediate proposals for this chassis to save costs are as follows:- Speedometer and Speedo. Drive. A.C. type instead of A.T. Saving £3. 6. 0. Ignition Distributor. Use Delco-Remy as on Bentley. Saving £1.14. 0. Ignition Coil. Use coil D.75673. Saving (Two coils per Chassis) 16/- Total saving over Wraith I = £5. 16. 0. ----------- Rm{William Robotham - Chief Engineer}/Wst. continued | ||
