| To R.{Sir Henry Royce} From Hs.{Lord Ernest Hives - Chair} Y4021 c. to Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c. to BY.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/VHl/LG23.2.29. WATFORD MAGNETOS ON F.{Mr Friese} ENGINES. Numbers R.H. 98034. L.H. 98033. These magnetos have now run 120 hrs. on RR. F.{Mr Friese} engines during which period they have given us satisfaction. The running time includes short runs to 2750 r.p.m. (approx. 15 mins.) at this engine speed we experienced no trouble of any kind. They compare very favourably with the B.T.H. in bulk and weight. It is proposed to fit these magnetos to one of the Type Test engines which is starting the test shortly. They are being returned to the makers for examination before the test.
