| W/S. {Derby Works / Sales} Sg. {Arthur F. Sidgreaves - MD} from Hs. {Lord Ernest Hives - Chair} X4367 Hs {Lord Ernest Hives - Chair} 6/LG18.3.26. not sent out SMITH - SPEEDOMETER. WINDSCREEN WIPER. We are running a Smith speedometer on a car. Actually the one we are running has behaved fairly well but we still do not consider that the principle of the Smith speedometer is anything like as good as the A.T. The fact that the Smith speedometer on 11-EX is giving such a lot of trouble is enough to condemn it because it confirms our previous experience and it is what we should expect. As regards the Smith windscreen wiper. We think it promises to be very good. We agree however with CWB. that it works rather too slowly. We think the correct period should be wipes per minute.
