| R.R. 493A (50H) (D.B. 175 25-9-24) J.H.D. -3- EXPERIMENTAL REPORT. Expl. No. REF: Hsl/LG18.12.24. The worm is also case-hardened. We consider that wear on the steering nut and worm will be practically eliminated on this car. (4) It is equal to the 40/50 HP. (5) 93-NK cannot be taken as a sample of instrument position. It is a 'V' fronted car which does not allow us to put the instruments in the standard position. The next EAC. car which is submitted to Sales, will have the instruments in the correct position. (6) The brake and change speed lever on 93-NK car are the 'W' series type - not 'V' series. 'V' series will be identical to the present 'U' series. It is anticipated on 'W' series that there will be no huge lever for operating the head lamps - the RR. scheme of dipping head lamps will be fitted. (7) The exhaust is more noisy than the old type 40/50 HP. (8) Yes. (9) 'V' series will be fitted with the standard 'U' petrol tank. (10) Ditto - as above. (11) " " " (12) Yes. (13) The controls on the steering column on 93-NK are the final design. The controls for the starting carb. however, are being modified. The final design will be on the next car. contd :- Handwritten notes: Next to (4) & (5): OK in V series Next to EAC. car: # we will correct. Next to (6): OK for V series Next to (7): OK till we can make it better Next to (8): OK Next to (9): OK in the present Next to (10): ditto Next to (11): ditto Next to (12): OK Next to (13): OK in the present | ||
