| -2- The magneto has now been returned and has passed the standard Works test as O.K. In view of the above report it certainly appears that this magneto is far from O.K., as, after running some miles it becomes practically useless. There is also another magneto No.75324 which has been returned by Cricklewood with a complaint of bad slow running. This has also passed the Works standard test, but since it has been returned as defective we cannot put it into stock. The above cases indicate that the standard test carried out by W. (at atmospheric temperature) is quite inadequate. Hm{Capt. W. Hallam - Head Repairs}/NRC.{N. R. Chandler} WPC | ||
