Re: Bentley Speedometer & Rev. Counter. Kindly note we are not sufficiently satisfied with the AC. instruments to release them for 'M' series, and we are issuing instructions for 50 speedometers and 50 rev. counters to be ordered from the A.T.Co. and Rm.{William Robotham - Chief Engineer} is going to order further A.C. instruments for experimental tests. By the time it is necessary to order further instruments for production, it may be possible to arrive at a decision as to the type required. Will BY/RD. please issue the necessary instructions.
