| X5661 EFC. BY16/H.{Arthur M. Hanbury - Head Complaints} 31.3.27. ----------- DYNAMOS. -------- We have arranged with Wor.{Arthur Wormald - General Works Manager} to put through 25 dynamos 20 HP. type, using the 28 slot armature. These will be extra to production, and will be put through with the object of determining whether the modification will, in bulk, give what the early machines show, that is, an improved machine from the point of view of silence. If the machines prove satisfactory, I will then put in hand 25 Phantoms, and on the basis of quietness I then consider we should be in a position to go ahead and produce both machines with the modified armatures.
