Hollingworth} c. to [redacted] c. to Rm. {William Robotham - Chief Engineer} [redacted] 602 HPS {Horace Percy Smith - Experimental Factory Mgr} /No.1/VS. {J. Vickers} 13.7.37. WRAITH III AND PHANTOM III BACK AXLE. Re your memo R {Sir Henry Royce} /Hdy. {William Hardy} 1/JR. {Mr James Royce} 18.7.37. suggesting alterations to sizes of holes on Axle tubes and End Plates. We do not anticipate any trouble whatever from the sizes recently agreed to by all concerned, i.e. .3125±.5 dia. which would appear to be an ideal figure and condition. .343 dia. holes have been tried and proved unsatisfactory. A somewhat similar result is anticipated from .324±.5 dia. holes, and we therefore suggest that no action should be taken unless trouble is experienced with .3125±.5 dia. holes.
