| To Hy.{Tom Haldenby - Plant Engineer} C. to Mx.{John H Maddocks - Chief Proving Officer} Ha/Wst.16/JH. 8.4.36. Noisy 20/25 Dynamos. We have now tested out an up-to-date dynamo fitted with a stiffened end bracket to drawing D.54798 using magnet case D.54799 and plugs for the screws to D.548xx. This dynamo has been found by the Test Dept. to be entirely satisfactory and free from noise. HS{Lord Ernest Hives - Chair}/Wst. | ||
