| X.4555 BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} DA{Bernard Day - Chassis Design}1/M11.2.28. RE. DIPPING HEADLAMPS. With reference to BY/CGH{W Clough}2/G7.2.28., 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 xx it makes a difficulty in cleaning the lamp. DA.{Bernard Day - Chassis Design} | ||
