| -2- Axle Control. The scheme with the shock absorbers moved out is not yet on test. Water Excluders. The results which have so far been obtained from these fitted to customers' cars and also to Bn{W.O. Bentley / Mr Barrington}'s car show that they are satisfactory. The Standardisation Sheet is still waiting for costs. We think this is a case where the usual procedure should be accelerated, because it is such an important improvement and will greatly reduce the chance of dangerous failures such as broken pivot pins. Brakes Fading. The scheme issued for this has not yet been detailed. However, we put the altered leverage on 5-B-IV made to experimental details. There were one or two modifications to the servo which have not been fitted. In view of the fact that it is put down as one of the worst features on the Bentley we think that this scheme should have been detailed. The 14" brake drums are on test on 5-B-IV. It is up to us to expedite the manufacture of the altered leverage, and we are going to do this. Isolated Change Speed Lever. Bn.{W.O. Bentley / Mr Barrington} and Lp.{Mr Lappin} express themselves to be perfectly satisfied with this; Hancock reports that the one fitted to 5-B-IV is also working satisfactorily. We are therefore circulating a Standardisation Sheet. So far this has only been fitted to Bentleys. We are not sure whether any difficulties will arise in applying it to the 20/25, but should like Design to look into this. Girling Brakes. We have demonstrated the Girling brakes fitted to 3-B-IV to E.{Mr Elliott - Chief Engineer} There is quite a lot of work to do to determine finally the advantages and disadvantages of this system, and we are continuing our tests. | ||
