| MX.{John H Maddocks - Chief Proving Officer} EFC. --- BY8/H.{Arthur M. Hanbury - Head Complaints} 2.12.25. ----------- 40/50 HP. CHASSIS. NOISY DYNAMO. U.G.15. --------------------------------------- Referring to Mxl/T.20.10.25. which I find got buried in my general correspondence, I am quite in agreement with the suggestion that we should hand this particular dynamo to EFC. for close examination to see whether there are any points upon which EFC. can give us guidance in regard to the complaint of undue noise. Would you kindly send the dynamo in question over to EFC. so that he can check same, to see whether there are any peculiarities in regard to the windings, commutator spacing or features of that description which in his opinion are likely to make it noisy. Upon completion of the examination, I would like the dynamo in question to be sent to Mr.Brock, with copy of his report. BY.{R.W. Bailey - Chief Engineer} [Signature] | ||
