I've got a Centurion Pro Tour 15 with a fork about that size (~8" of steer tube). Unfortunately, the bike was in a front end collision that put a slight bulge in the top and down tubes. I haven't taken the fork out to check it but it looks OK (It's still in the bike, turns a bit tight). It's a steel fork, of course, so it could be repaired if needed. It's a real touring frame - and a nice one, shame about the frame damage - so the fork has all the nice touring braze ons. PM me if you're interested.
