| 1305 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/FWK.14/JH. 22nd. February, 1939. Toledo Woodhead Spring Co.Ltd., Toledo Steel Works, SHEFFIELD.1. For the attention of Mr. Frank Woodhead. Leaf Springs. Dear Sirs, We are considering using a 56" spring in place of our existing 50" spring FB.4271. This contemplated spring would still have a 7" deflection under 1000 lb. load with 6½" free camber. Before we order a pair however we would like to know what increase in weight there will be if any, due to the increase in length. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
