| 18 / CHASSIS 1926 GENERAL SUMMARY General summary:- The filling in of the dashboard certainly increases the tendency of the water to boil as compared with the dashboard open and also the side louvres fitted. floorboard temperatures are generally lowered as also is the temperature inside the body. Tests still show however that the effect of forming a pressure inside the body reduces the temperature inside the body considerably. Test also shows that [struck through]although[/struck through] there is no report of any objectionable smell inside the body it being considerably less objectionable than when the dashboard is not filled in. There is however still a tendency for air to be drawn into the body shown by the fact that when the footbrake is used excessively burnt oil smell which comes from the brake can be smelled inside body as in previous tests.
