| -2- (b) Cont'd.{John DeLooze - Company Secretary} Rm.{William Robotham - Chief Engineer} said that the raw material cost of the shell weighing 224 lbs. at 2d. per lb. was 37/- say £2., and that the rest of the cost was therefore due to wages and would be susceptable to improved production methods. It was agreed to be fair to assume that if the body were tooled up to the extent of £50,000 the tool charges would be £10. per body and that the shell complete would be obtained for £28. i.e. a saving of £22. over the present semi tooled F.. construction plus the wages of putting the latter together. The labour cost on B.V. is £9. plus £9. over- heads. It was suggested by Mr. Green that a finish shell made by F.S.C. to their construction would cost £40. on a quantity of 5,000 bodies and we can assume a saving of £20. on the metal shop section. (c) Costs - Wings. Mr. ard said - (1) Front wings cost £15.12.0. in alum & £13.0.0d in steel. (2) Front and rear wings in alum. cost £20. with £3. labour and £3. overheads is £26. per set. All of the above for batch of 250 sets. Mr. Green said :- Daimler 1/. Front wings Tools £2542. Rear wings Tools £962 ----------- £3504. Also Daimler. 1/.
