| To Da{Bernard Day - Chassis Design}/Thr. from EFC. X4291 EFC5/T19.4.21. X.4291 - DIMMING DEVICE FOR HEAD LAMPS. We do not know whether you have in any way acted upon the instruction contained in our EFC4/T13.1.21, but we have two experimental head lamp dimming devices on which a report is being sent independently of this note, so that we think for the time being you might hold this matter over.
