| To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to CJ. c. to Rg.{Mr Rowledge} c. to E.{Mr Elliott - Chief Engineer} c. to De. c. to FN. Handwritten: 1st MENTION OF FWB ORIGINAL 4-WHEEL BRAKING. X4428 We attach herewith a copy of letter we have received from Monsieur Henri Perrot, dated 3rd. Nov. As Mr. Hs{Lord Ernest Hives - Chair} is in London, we have replied asking what is the nature of the tests and whether it would not be possible to see the car in London. We consider that as the "perrot" system is used on about 50% of the cars fitted with four wheel brakes, we ought to be able to obtain valuable information from Monsieur Perrot.
