Coverley - Production Engineer}/CAN.1/LS.14.6.39. which covers a comparison between front suspension pieces on the Wraith and on the B.V. For a basis of comparison, the front suspension of the first 200 cars has been taken, photographs of which are attached. The Wraith parts with which these are compared are photographed in the Wraith weight analysis file, a copy of which By.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} and RHC.{R. H. Coverley - Production Engineer} have. It will be observed that the material cost of these parts for the B.V. comes out @ £14/15/7. We consider that the Engineering Dept. must take responsibility for material cost and that this figure is too high. In view of this fact, a discussion was held between By.{R.W. Bailey - Chief Engineer} Les.{Ivan A. Leslie} Rm{William Robotham - Chief Engineer}/AFM{Anthony F. Martindale}, RHC{R. H. Coverley - Production Engineer}/CAN. and Rm.{William Robotham - Chief Engineer} to see what prospects there were of reducing the figure of the parts in question. It was unfortunate that RHC{R. H. Coverley - Production Engineer}/CAN. was unable to be present at more than a portion of the discussion owing to pressure of other work. One point that immediately arose was that the final rationalised front suspension would have the benefit of the semi-floating hubs which had already completed 50,000 miles, and that this would reduce the material cost by 30/-. The shock absorber material was first considered, and the following reductions were thought to be possible before we order the thousand sets of material in February:- | ||
