Will you please make us 12 valve springs to EB.3256 produced in the normal way and 12 to EB.3256 shot blasted, both sets of springs to be in "Swedish Wire". We should like to get these as soon as possible in order to be fitted on our special long distance test. The two types should be coloured to distinguish and handed to self in order not to get these confused with other springs. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
