| Fm R12/B14213 In testing the strength of the back axle by the bumping (by log) I have the impression that we used present system of inverted springs to control the axle sideways and that they performed this duty without shewing any distress or the axle shewing any signs of moving sideways due to their want of control. if, however, the ¾ elliptic were used, please at once arrange a test to be made on our present standard springs and fitting. the new light axle might be used in this test - two tests in one. x 137? | ||
