| Hs.{Lord Ernest Hives - Chair} Rg.{Mr Rowledge} EFC. c. Sg.{Arthur F. Sidgreaves - MD} c. Wor.{Arthur Wormald - General Works Manager} X4021 By 5/G24.9.29. X 4513W. AERO ENGINE MAGNETOS. In view of EFC2/AD20.9.29. we would suggest that the time has arrived for issuing a standardisation sheet covering the use of the Watford magneto on our aero engines. We are not happy with B.T.H. as there is always a difficulty if any improvements or suggested modifications are under consideration, and as we use Watford magnetos on the cars it would be more consistent if we similarly, now that they are available, used Watford magnetos on our aero engines.
