| ORIGINAL TO CJ. (struck out) FROM R.{Sir Henry Royce} Copy to - BJ (struck out) HS.{Lord Ernest Hives - Chair} AIR CLEANERS. X.3812 (handwritten) Air cleaners are not much needed for England with our dustless roads, and we cannot fit all the devices that can be thought of, because of weight, complication, and cost, and I very much doubt if any of the devices I have seen would catch 10% of the dirt: they may be a selling cry.
