| Y6014 To-R. {Sir Henry Royce} from E. {Mr Elliott - Chief Engineer} E.9/HP.1.11.32. C.c. Sr. Sor. Hs. {Lord Ernest Hives - Chair} Ev. {Ivan Evernden - coachwork} Dn. Vibrator Control, Distribution Board. For a number of reasons we were not satisfied with the last design sent to you of the above, the field resistance protruding rather a long way, and was hung on brackets which had an unsatisfactory base. It was provided with external looped connections, and had to be removeable for the purpose of making a cable connection, which was otherwise blanked off and inaccessibly situated in the recessed base of the moulding. The remaining connections and the strap for securing the regulator were also not all that could be desired. We now attach a further blueprint - D. {John DeLooze - Company Secretary} Sch. 592 in which the former objections have been overcome by a rearrangement of the units in the top part of the box. We believe the result is much more orderly, and accessible. Features have been added also to prevent the pail handles being operated in the wrong direction. A blueprint of D. {John DeLooze - Company Secretary} Sch. 592 is attached to Dn's copy of this memo, so that this distribution unit can be considered in relation to dashboard assemblies.
