| x3035. Roy.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. Wor.{Arthur Wormald - General Works Manager} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/AD25.4.32. We require a Jaeger chronometric tachometer similar to the one we are at present running on our car test beds. The revolution counter reads up to 6,000 R.P.M. in two complete revolutions of the hand and is fitted up with a 2 : 1 gear ratio. The number of the kind we already have is 27184. We also require one Hasler revolution counter. These are for use on the additional test bed we are having to fit up in order to run the J.3. unit.
