| To HS.{Lord Ernest Hives - Chair} } FROM DA.{Bernard Day - Chassis Design} To BY.{R.W. Bailey - Chief Engineer} } X. 8940a X. 8420 We notice that the 10,000 miles car has still the front brake differential one one side. Some considerable time ago we did a differential across the back of the clutch casing. We wonder what point this has reached, and whether there is any possibility of it going on test soon.
