The C.575a dynamo, being of Lucas make, can take the place of the E.575 without any other alteration to the system, and in this respect would be suitable for more immediate standardisation than the Smith dynamo. On the other hand, owing to its being a concentric machine, the range of adjustment for belt slackness would be reduced. EFC. | ||
