Wor.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} Mr. North. XS.790 R1/M15.4.27. REC'D DURING EASTER, AND DESPATCHED 20.4.27. MAGNETOS- 40/50 & 20 HP. X.5790. X.7791. x 5792. I believe I have written about the above, and I understand we are waiting for Watfords for - (1) A magneto for Phantom, sleeveless, as the small one I have seen - i.e. laminated poles giving satisfactory spark when retarded at slow speed, so that the battery failing the engine can be started by hand. (This happened at Le Canadel owing to broken step-iron, which has now been altered I understand). (2) A magneto for [crossed out]Phantom[/crossed out] 20HP, preferably sleeveless, because it is not worth the complication and expense. It must spark at slow speed for easy hand starting as (1), and also should perhaps be of the inductor type, so as not to destroy our jump spark distributor. If we cannot get a move out of Messrs. North & Co. we must go elsewhere - i.e. B.T.H., Lucas. Please send Mr. North a copy of my memo. R.{Sir Henry Royce} | ||
