We have now completed two endurance tests equivalent to 10,000 mile tests on two of the above type levers, these being the latest lever with the 20/25 HP. type of spring used on Bensport. Both levers completed the test satisfactorily, the wear on the points and on the rubbing block being quite normal. Hs{Lord Ernest Hives - Chair}/Wst. | ||
