| -5- The front and rear springs have been dismantled and all leaves examined. The front spring leaves were well lubricated and shewed very little digging in at the tips. The rear springs were found to be rusty on all but the two bottom leaves for a length of 6" from the end tips. The cadmium plating had been rubbed off and plates scored. All leaves were sound. | ||
