I assume you don't have Forty Years On and Another Ten Years, because both contain lots of ingenious mods designed to improve the original design including sealing improvements to eliminate leaks. They're worth buying even if just to find out that there's nothing new under the sun! What the mods can't do is bring a pioneering design, revolutionary in its day, anywhere near the standard of a modern damper. Mine didn't leak, but they didn't damp effectively either, so I bought Thornton dampers which are a night-vs-day improvement.
