| To Wd. {Mr Wood / Mr Whitehead} from EFC. {E. Fowler Clarke - Electrical Engineer} X8796 EFC {E. Fowler Clarke - Electrical Engineer} 1/T12.1.25. X.4181b - WATFORD MAGNETOS WITH NEGATIVE ROTATION AND 60° RANGE. Referring to your Wd {Mr Wood / Mr Whitehead} 5/NJ7.1.25, we have now received back the three magnetos Nos. 68109, 70037 and 73973m and we find that the two former ones are not fitted with an up-to-date H.T. collector brush. Accordingly we are handing you these two H.T. collectors and perhaps you would make arrangements for these to be exchanged for the up-to-date collectors, as it is our desire to have these magnetos up-to-date in every respect for experimental test. Longer securing screws also required. Cancelled. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
