| (COPY) X5310 SECRET. TO By.{R.W. Bailey - Chief Engineer} from BJ. BJ7/H4.3.25. INDIA. 4-SPEED BOX. I appreciate the position mentioned in BY3/H3.3.25. What we really want to do is to have an opportunity in London of trying a 4-speed box as soon as the Test Dept. are satisfied with it, as so far we have never been on a 20 HP. with a four speed and shall be interested to see what it is like to drive.
