| To Wd {Mr Wood / Mr Whitehead} /GEA. from Hs. {Lord Ernest Hives - Chair} V4308 Hs {Lord Ernest Hives - Chair} 3/LG25.2.26. A.T. SPEEDOMETERS. With reference to the 2 A.T.Speedometers Nos.16626/7. These speedometers were not run on a car by us. The only car on which it would be worth while fitting the speedometer would be one which was about to start a 10,000 miles test. We have not had an opportunity to fit these speedometers to such a car. If the A.T. people will supply us with a 20 HP. speedometer, we shall be starting a 10,000 miles test within the next 2 or 3 weeks, we could then arrange to fit the speedometer to this car and let them know the results.
