There are certain experimental cars (cylinders of some have had special treatment) which have completed a sufficiently useful mileage, of which we require measurements of the bore wear. They are as follows:- At Derby (Hd{Mr Hayward/Mr Huddy}) 25. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} Vl.{V. Lewis / Mr Valentine} (Chrome plated bores) Although this car has to date only completed between 5,000 - 6,000 miles, we wish to inspect the bores, for fracture of the chrome. 24.
