To Rm{William Robotham - Chief Engineer}/FD.{Frank Dodd - Bodies} from Rm.{William Robotham - Chief Engineer}

Rm.{William Robotham - Chief Engineer}1/MH.{M. Huckerby}16.3.40.

4.B.50.

We should like you to adjust the speed recording mechanism of the speedometer on this car so that it represents the normal standard that we sell to the public, which is between 3 and 6% fast.

We believe this can be done without altering the odemeter.

11.B.V. seems to us to be about the right amount fast.
