Further to BY.11/G.22.9.31. we were under the impression that something had been done, and we now find that Sch. 992 was detailed and instructed by BY/CS.1/DB.{Donald Bastow - Suspensions} 5.12.27. We think it is essential to try one of the Dunlop belts on this particular drive in order to ascertain whether the same conditions would arise as occurred in France and with Mx.{John H Maddocks - Chief Proving Officer} on test.
