| 1676. S/W To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} re Jaguar. Sg{Arthur F. Sidgreaves - MD}1/E13.4.38 We noticed amongst other things that this car had two separate exhaust manifolds and pipes as distinct from our scheme. Doubtless you will be testing this from the point of view of ascertaining whether it improves the performance and we shall be interested to hear the result. Sg.{Arthur F. Sidgreaves - MD} | ||
