| EFC. X 7791 9.8.27. X8743 We have changed the Lucas magneto fitted to 9-EX. to 10-EX. The Watford sleeveless magneto (No.98201) which was fitted to 10-EX has been fitted to 9-EX. We have made this change owing to the superiority in quietness of the Lucas magneto, the Watford make and break is decidedly more noisy than the Lucas, and we require a quiet magneto on 10-EX before it is sent to R and BJ. Speedometer readings when changed :- 10-EX 4618. 9-EX. 6234. A.J.Lidsey. | ||
