| contd:- -3- reliable for the reason given below and I should like to see us be able to hold the car by the foot on a 1 in 5 gradient. P.N. I was pleased to hear that PN.{Mr Northey} had some 4-wheel brakes but I have not heard where he is on his journey here. I hope to hear he is getting along alright very soon now. After a severe mistral the weather is getting better. R.{Sir Henry Royce} | ||
