| 800 also 400 SECRET. Sg. {Arthur F. Sidgreaves - MD} from Rm. {William Robotham - Chief Engineer} Hs. {Lord Ernest Hives - Chair} c. By. {R.W. Bailey - Chief Engineer} ___________ Rm {William Robotham - Chief Engineer} 4/R.23.6.38. B.50 went over on the road as a complete car on Tuesday, June 21st. As is the case with every prototype 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.
