Sidgreaves - MD} Mor. c. to E.{Mr Elliott - Chief Engineer} Da.{Bernard Day - Chassis Design} c. to By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/West.C/WJ.14.10.31. AMMETERS FOR CHASSIS. Some time ago you wrote suggesting that we should use moving iron type of ammeter which would be very much less expensive than the present type, and more robust. In our opinion they are sufficiently accurate for anything we need on a car. We should like to know whether you are in agreement that we could obtain an ammeter of this type to suit our instrument board. Hs{Lord Ernest Hives - Chair}/H.S.West. | ||
