| To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} 350 Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}3/AP.31.8.37 PHANTOM III. STEERING. We wish to be able to try a lower geared steering on a Ph.III. fitted with the Wraith type steering box. We have ordered the special cams required from Adamants and have received from them the attached print, M.22015, showing the details of the outer contour of the roller follower. Will you please make detail and assembly drawings of this roller but with inner races and ball tracks exactly as on the Wraith roller, FW.911. We show roughly in pencil on the print the section of the roller with this arrangement. We wish to order three of these rollers from Hoffmanns. Rm{William Robotham - Chief Engineer}/FJH.{Fred J.
