| x1640 To EY. from DA{Bernard Day - Chassis Design}/T. DA{Bernard Day - Chassis Design}/T1/G10.8.21. c. to Hs.{Lord Ernest Hives - Chair} c. to EFC. X.4383. RE "COSHAWK II" MOTOR AND DYNAMO X.1640. X.4384. Would you please issue the necessary information to the experimental dept. to enable them to make up a dummy model armature complete with winding on each of the above machines, as per Mr. Royce's instructions. The armature itself should be made of wood with the slots cut in and mounted on a rough spindle, then wound with the insulation and winding which we have already instructed to you. The object is to see whether the winding can be got into the estimated space or not, etc. and we wish these armatures to be sent to "CamachaHenry Royce's office in West Wittering" as soon as possible. Also please send further copies of the winding drawings on above windings for our information. DA.{Bernard Day - Chassis Design} F.R. 286A (100 T S) (H.{Arthur M.
