| To By.{R.W. Bailey - Chief Engineer} & Rm.{William Robotham - Chief Engineer} from RHC{R. H. Coverley - Production Engineer}/DWB.{D. W. Brown} c. RHC.{R. H. Coverley - Production Engineer} c. LA.{L. A. Archer} c. BY/NS.{Norman Scott} c. Rm{William Robotham - Chief Engineer}/Wyn. WRAITH - MOULDED GAP PLATES. Further to your memo' reference BY.10/G.17.3.39, in connection with the above. In addition to those which were sent to the Experimental for test, samples were also supplied to LA.{L. A. Archer} for fitment to test chassis. LA.{L. A. Archer} reports that he has fitted his sample plates to some twelve different test cars and has experienced no trouble due to the plates breaking during fitting. There is one point which suggests that those samples which were tested by the Experimental Department, were not fitted to the chassis in a normal manner - namely that owing to an error of the mould-makers, the .281" dia: countersunk hole in the bottom flange is .5" out of position, and could not therefore match up with the normal fixing for this part. No additional hole had been drilled in any of the broken samples received from the Experimental Department., so that it appears that they have been secured by the top flange only. In view of the satisfactory results obtained from the Test Department we are continuing the tests and are, in the meantime, contacting the makers with a view to ascertaining whether a slightly more pliable material can be supplied.
