| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} C. to H3. ORIGINAL DA{Bernard Day - Chassis Design}1/M11.2.28. RR. DIPPING HEADLAMPS. YU555 With reference to BY/CGH{W Clough}2/G7228., we send herewith N. sch. 2545 shewing the proposed locking on the spherical nut of the hinge bolt. It is thought that though the castle nut and split pin could be used it makes a difficulty in cleaning the lamp. DA.{Bernard Day - Chassis Design} | ||
