| SECRET. 406 Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} Hs.{Lord Ernest Hives - Chair} c. Hy.{Tom Haldenby - Plant Engineer} c. RHC.{R. H. Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}3/R.20.4.38. At a recent interim Conference when the Girling brakes were discussed, we suggested that as a lot of the B.IIA Girling brake parts would be common to B.III, these pieces should be introduced on the last 100 old type Bentleys. A more detailed investigation of the tool charges involved shows that, in practice, we shall be committed to just over £400 tool cost, which will be useful only for Bentley IIA cars; on the other hand, the saving per car is estimated @ £14. In other words, the total saving to the Company by bringing in these brakes might be expected to be in the region of £1,000. Should more than 100 cars be made, this would, of course, be increased. It is possible also, that due to the change in design further economies might be introduced into Shop practice. Experimentally, we should like to get these brakes on to production to get experience, as though parts are not exactly interchangeable, the general layout is almost identical between B.III & B.50.
