| R.R. 493A (40 H) (SL 42 12-7-23). J.H., D.{John DeLooze - Company Secretary} ORIGINAL Expl. No. 4594 REF: HES/LC11.10.23. EXPERIMENTAL REPORT. To 10,000 MILES TEST ON 20 HP. PRODUCTION CHASSIS - 79-AO. Attached herewith is a record of the performance taken every 1,000 miles, details of the faults which occurred on the 10,000 miles and details of the adjustments which were made. The general running of the car after 10,000 miles was extremely good. The engine gears and axle were very good for silence. The chassis is also exceptionally free from noises and rattles. We anticipate that very little wear will be found when the chassis is dismantled. Hs.{Lord Ernest Hives - Chair} | ||
