We are anxious to keep an accurate record of all the Thermoid faced cushioned clutch plates fitted to customers cars, so as to observe their behaviour in customers hands. In order to confirm our records, would you kindly send us a complete list of all those you have fitted, with date and if possible speedometer reading. There may be cases where we have sent a plate for a particular car to which you have not been able to fit it, such as Bahawalpur 3-AX-87 which was ultimately fitted at Derby.
