| X6006 RHC.{R. H. Coverley - Production Engineer} from EFC. EFC2/AD16.10.30. X.6006. 48 COIL HIGH OUTPUT DYNAMO. We require two 48 coil armatures to replace in two present production machines at present fitted with 56 coil armatures. In view of the experiments at present in progress on the improvement of dynamo performance, we require these machines fitted with 48 coil armatures only i.e. in the first instance without the pole piece modification. Will you please arrange for this. CAP. EFC. | ||
