| To BY from BJ. BJ2/E8/11/27 - 2 - carrier has received in actual practice on the road in its present form is not mentioned by you. 3. Pressed Steel Wingstays. This is mentioned in my memo. to Wor.{Arthur Wormald - General Works Manager} of yesterday. 4. Battery in Frame. do do do 5. Grouped Instruments. do do do (BJ10/E7/11/27) 6. Radiator with Integral Shutters. We have no record of what tests have been made of the present design with an ordinary heavy body to ascertain what is the actual difference in cooling capacity on the road over long periods at high speeds and during long mountain climbs or other trying conditions where our engines have been noted for overheating in the past. Presumably tests could be made taking the temperature of the atmosphere and the increase in the temperature of the water to enable us to compare what is likely to be the result when the atmospheric temperature is at, say, 85. Part of our 10,000 miles test is always to include some severe mountain climbing with the car being driven by an amateur, also the car being run over long periods in London traffic. These practical tests have always been found to be essential to arrive at actual results. We presume that the two most important items are axle control and wheel carrier at the back. The first is agreed and perhaps you could make arrangements/to test the second at an early date to enable it to be included half way through the F.2. series. Presumably the above will be sufficient to enable material for F.2. series to be put in hand without further delay. BJ. | ||
