| - 3 - We are attempting to fix the 40/50 shock absorber ball ends to 7-G-II about which new instructions have been issued. Leaking of oil from the steering column is rather a weakness noticeable on 7-G-II, probably worse as this column was specially filled with Amber gear oil. R.{Sir Henry Royce} points out the starter switch barrel should be made of copper and not bronze and if properly fitted should make good contact. Have you had trouble with these? I understand from Mr. Coverley that the barrels of 4, 5, 6 and 7-G-II are made of copper, although the instructions appear to call for bronze. (Handwritten insertion: G4 was certainly made of bronze, we mean the turned collar not the [illegible]) (Handwritten note): The springy problem. On 4G I took it apart to see how it was going on. We found no oil in it, the contacts burnt on one side. I consider we ought to use engine oil on these switches, if possible it would be less complicated. The rattle in the drive of the dynamo on 7-G-II, I should say is worse than on 4, 5, & 6-G-II and is distinctly noticeable when running along the road at a slow speed or engine "idling". The slack in the drive I also feel is rather worse than on the other cars. Do you think we should tackle this slack and reduce same to a minimum, as in any case one rather has the feeling that it may develope- badly when in the hands of customer. How are 4, 5 and 6 shaping in this respect. (Handwritten note): I tried to chase this rattle to R on 6G & it was not however very bad. It is up to us to find out the definite cause & a definite cure. I would suggest first trying to see how much braking is required to prevent it, or if a fabric joint is used it disappears, & will certainly not be tolerated by customers. Are you satisfied with the action of the hand control lever for the throttle. Do you not think this is still too sudden. Could we still further reduce the leverage or use a smaller notch on the control quadrant. (Handwritten note): I think this point could be improved EP.{G.
