| 400 also 800 SECRET. Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} Hs.{Lord Ernest Hives - Chair} c. By.{R.W. Bailey - Chief Engineer} B.50 went over on the road as a complete car on Tuesday, June 21st. As is the case with every proto-type experimental car, a number of adjustments will have to be made before it is possible to get a fair impression of its merits. We have completed 50 hours endurance running on the new small gearbox without a major failure. The first B.III is now being re-built with more up-to-date parts, and we expect that it will be available for trial by Sg.{Arthur F. Sidgreaves - MD} about the end of the second week in July.
