X.1179 X.1232 Replying to Mr. Elliott's memo E2/G17.2.20. the proposal to use solid eyes on the rear springs was first put forward in your note R8/P24.3.14, At this time a new shackle for the front end of the rear spring with its anchor bracket was under consideration, and you sent along a design in which the solid eye was used, the reason given being that it greatly improved and lightened the shackle. This improved shackle with the solid eye necessitated by it, was embodied in the thick leaf springs, and these thick leaf springs, subsequently split, were included in the general instruction for the after-the-war-chassis given in EH2/LG19.9.17. This is the history of how the solid eyes on the rear springs came to be used. | ||
