Harold Whyman - Experimental Manager}: file copy in new Frazer Nash car file [Handwritten top right] 1067 24th April, 1941. re:- B.24.AW & Mr.Minchin's B.M.W. B.24.AW. behaved quite satisfactorily through-out the journey to Park Wards. The speed of the car was kept reasonably low for the whole journey because of the new cylinder block having been fitted. The only point about the car open to critisism was a slight nibbling on the steering wheel when running on a secondary road, but one would not call it objectionable. We were not able to collect Mr.Minchin's B.M.W. from A.F.M. Motors, Ltd., because the car had apparently been sold the week previously and they were not prepared to enter into any agreement to loan us the car. [Handwritten initials in red] Om Capt. Nash's B.11. This car is a B.11 with overdrive, and the complaint was that the car would not run satisfactorily on Pool petrol. I tested the car with the chauffeur and found it quite a normal example of a B.11 running on pool petrol. There were slight detonations on pick-up from 10 MPH to 20 MPH and nothing after. The ignition timing was checked and found to be 2° early. This was corrected to standard. One other point was raised, and that was the chauffeur complained that he had difficulty in changing from 3rd to 2nd speed. The main trouble here, was the bad method of changing employed by the chauffeur. He delayed his change and did not use his engine revs. The gear lever also fouled the corner of the slot in the gate. Capt. Nash asked if it would be possible to reduce the compression ratio by fitting two gaskets, but I informed him that this was a departure from a standard car and that the Technical Dept of R.R. should be consulted. The car has run just over 6,000 miles. L. Ward. | ||
