| To R. {Sir Henry Royce} from Hs. {Lord Ernest Hives - Chair} c.c. to EJ. Mor. ✓ c.c. to RO. {C. C. Rose - Export Manager} E. {Mr Elliott - Chief Engineer} ✓ c.c. to DA. {Bernard Day - Chassis Design} EY. ✓ PHANTOM THROTTLE. L8140 We have had a car running fitted with the roller bearings in the throttle spindle. The lag on the governor control is very considerably reduced - it now only amounts to one notch on the hand control lever. It very closely approximates to the Silver Ghost(1907 40/50 historic RAC 15,000 miles trial) control. Hs. {Lord Ernest Hives - Chair} | ||
