| ( 2 ) GWH{George W. Hancock - Head Chateauroux}/IMW{Ivan M. Waller - Head of Chateauroux}/4/JAB.15.6.36 Percentage Decrease in temperature With New Radiator. Water Under Bonnet Air. 35 MPH........... 8.9°C 3.8°C 60 MPH........... 11.1°C 5.4°C Full Throttle.... 12.4°C 4.1°C It will be noted that with the increased efficiency of the new type radiator, the under Bonnet Air Temperature has not risen, in fact it is a fraction lower. It should be pointed out, that the first radiator has been in service 19,000 miles (as per Log Book) while the other is new and clean. If Std. can give us figures of the water flow through the first radiator, we could check it over. We shall continue our daily running with the new radiator, so that our general running temperatures will give a further standard of comparison. BODY WORK. As stated in our Daily Reports, we have been experiencing bad sticking of the doors. The real cause of this trouble would seem to be a general set in the coachwork, allowing the doors to fall out of line. The valence at the bottom of the N.S.R. door is cracked away from the door pillars, and there are general indications of the middle of the body sagging. When the car is jacked up under the chassis frame midway along each side, the doors open & close freely. We attribute all this to the fact that the chassis is not fitted with tie-rods. BONNET SIDE STRIPS. The screws securing these, continue to work loose in spite of repeated tightening, as a result of the continual pull of the rear bonnet catch combined with general movement on bad roads. BRAKES. The N.S.F. brake adjustment is taken right up and the O.S.F. adjustment is 3/4 used up. These brakes have covered 6869 miles. Inspection shows that re-lining is necessary. The rear brakes have covered 10,780 miles and the adjustment is 1/2 to 2/3 used up. We are alarmed at the rapid wear of the front brakes and put it down to the considerable increase in acceleration & maximum speed of the car compared with the small bore engine, necessitating more frequent use of the brakes. ------------------- GWH{George W.
