| EWT. For CY. from EFC. {E. Fowler Clarke - Electrical Engineer} X.4285. EFC {E. Fowler Clarke - Electrical Engineer} 1/T15.4.21. X.3916 - U.S.A. BOSCH TYPE ZR.6 MAGNETO. X.4285. Apparently Mr. Hives only brought back with him one U.S.A. Bosch ZR.6 magneto of the latest type, and this one was completely disassembled and set out on a board for Mr. Royce's inspection. At any rate there is not one of these available for comparative tests as suggested in your note Oy1/G30.3.21. It would probably be as well to send us another of these magnetos, particularly in view of our recent report to you of the failure of a portion of one of these magnetos, which portion was sent to you. Perhaps you would also kindly arrange to send a replacement portion and also we should be glad if you could arrange to send the necessary parts of the D.U.Z.6 Bosch magnetos to enable us to bring these up to date in the manner referred to in your Oy2/G4.3.21.
