| W Hs {Lord Ernest Hives - Chair} Y4069 EB/M23.5.22. To Ba. from MAY 24 1922 c. to Sdr. c. to Wor. {Arthur Wormald - General Works Manager} c. to Hiv. c. to Ha. REC c. to EFC. {E. Fowler Clarke - Electrical Engineer} REC X 4333 X4069 GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. ELECTRIC MOTOR. We send you herewith drawing No. Lec 1585 showing the commutator for Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. starter motor built up in the old fashioned style with micanite insulation and steel cones. It is expected that you will be able after performing the usual operations to press the 2 pieces of the metal centre together with such a force that they will hold by themselves during the riveting up process shown on the inner end. Mr. Royce would like you to alter the design sent through for this type of commutator on the dynamo, replacing the thread and nut with the riveted up form of end shown on Lec 1585.
