We are sending into the stores the above rev counter. Will you please arrange to return this to the A.T.Speedometer Co., to have the dial changed for an up-to-date one, and have the calibration made correct at 4500 R.P.M. at 35ºC. We should like them to make a special job of this by calibrating it in Messrs.Smith & Sons Electrical Laboratory at Cricklewood using their Stroboscope as this speedometer is required for a very special car.
