| Mx.{John H Maddocks - Chief Proving Officer} From Hs{Lord Ernest Hives - Chair}/Wst. Y6051 Hs{Lord Ernest Hives - Chair}/Wst.4/MA.12.7.35. BENTLEY AND 20/25 CHASSIS NEW TYPE SPEEDOMETERS. We would recommend that no attempt be made to open up these speedometers or alter the calibration. These speedometers incorporate a new type magnetic system which is more sensitive to demagnetization when disturbed than the old instrument. If an instrument is found to be wrong it should be returned to Messrs.A.T. who have now guaranteed a 48 hour service on instruments of this type. Hs{Lord Ernest Hives - Chair}/Wst. | ||
