| - 6 - glasses are less splinterable than the old ones and they do not turn yellow with age. I will learn more about these and let you know. Your Item No.2 (Headlamps) American headlamps are not going to have separate shells from now on, but are going to be built into the front fender. The "package" type of headlamp is now standardized and will be obligatory by law in 1942. Imported cars will have to have package headlamps of the legal type for driving on the righthand side of the road. I understand that considerable freedom is to be allowed in the form of the external lens which is visible from the outside. It appears to me that R.R. will have to conform to the general tendency for building the head lights into the fender structure. Will consult with Guide Lamp Division on this subject. I, therefore, shall have to write you later on : Headlamps Heaters. Air Cleaners. Glass. Automatic Choke Truck Developments. With further reference to torsional stiffnesses, I suggest that most progress can be made in this matter by setting up a cabriolet car with the wheels off it on a torsional measuring rig in some quiet corner of the shop and for a couple of fellows to work on it until they get a torsional stiffness of not less than 3000, and preferably 3500 pounds feet per degree, with the torsional deflection fairly evenly distributed along the length of the body-frame structure. When they get this done and put the car on the road, if there still exists any considerable shake, it will be found in the front wheel action, rear axle tramp, or oscillation of the engine mount, of which all three are best studied on the bump rig with a good stroboscope. Sincerely, Maurice Olley. Enc. | ||
