I just bought a frame that came with the original Look HSC fork (after the subsequent HSC-2, HSC-3, ... were introduced, it was dubbed the HSC-1) It has a 1" threadless steerer made of carbon. I have my headset installed but I don't have the in-steerer anchor for the stem tightening bolt. On alloy steerer threadless forks, this role is taken by a star nut, on the Alpha-Q carbons it's an aluminum sleeve that is epoxied in. I have familiarity with those systems, but apparently this fork is spec'ed to use a compression plug.
Since neither the Look branded compression plug, nor any other substitute is available locally, I researched a few options. FSA, Reynolds ("Ouzo") and Profile all make a compression plug that works with 1", and Nashbar sells a house-brand unit as well as the Weyless.
Do the experienced denizens of this forum have a recommendation among these or for that matter not among them as my best bet for getting a long life out of what looks like a low mileage Looks HSC? I even have considered springing for the True Temper Alpha-Q sleeve, as that is certainly a stable setup, as long as the user is happy with the initial ( final ) placement. Many thanks.
One link that has a few options on it is:
