| X.5454 SIDE STEERING TUBE SPRINGS. F.54584 DA.{Bernard Day - Chassis Design} remarks :- Agreed on the understanding that F.54584 will be slightly modified in accordance with N.sch.2328 so that the more flexible springs with greater movement on N.sch.2308 can be fitted as soon as tests shew that they are satisfactory, the object of this being to avoid a further expensive changeover.
