| F.{Mr Friese} Dodd - I have not experienced this; have you? Rm{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer} at W. 1247. Hn{F. C. Honeyman - Retail orders}2/AH.9.6.38. Mead Ventilation: ---------- As I think you know C's 25/30 Car is fitted with Mead ventilators to the front windows and C is of the opinion that they encourage the entry of fumes into the body. He states that on several occasions he has felt very drowsy after a fairly long run at moderately high speeds whereas before the addition of the Mead ventilators he never suffered from drowsiness on the longest run. His passengers have also complained of this feeling in the car. Before the fitting of the Mead device C was in the habit of running the car with the front windows right down when of course there was a constant current of air swivelling around the interior and it is possible that he misses this. Does your experience with the Mead ventilating scheme lead you to think it may induce the entry of fumes please?. Hn{F. C. Honeyman - Retail orders}/= | ||
