| Mr. Wilkins (A.I.D.) c. Rg. {Mr Rowledge} c. Hs {Lord Ernest Hives - Chair} /CEP. c. Roy {Mr H. Royce - Buyer} /Dn. X4021 EFC {E. Fowler Clarke - Electrical Engineer} 2/T15.4.29. WATFORD IS.12 AERO MAGNETOS. Nos. 83132/3. In accordance with Roy {Mr H. Royce - Buyer} /Dn7/BH10.4.29, we have duly received these two magnetos. We find on inspection that these magnetos have not been altered to 300° range but are still of the old 15° range. We do not know whether Mr. Wilkins is aware of this fact, but it would seem to render these machines useless for the majority of test purposes. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
