Some confusion has arisen on production and also with the A.T.Speedometer Co., regarding the correct calibration for speedometers for the standard 20/25 Chassis 1150 Axle. We attach herewith the correct calibration of this speedometer which should be circulated to the Test Dept., in order to avoid error in sending speedometers back to Messrs.A.T.'s This calibration has also been handed to Mr.Buckland of the A.T.Co., who discussed this matter with By/RD. and ourselves this afternoon.
