True, true...and WELCOME BACK, T-Mar!!!
It's still a stumper but are we certain that the fork is original?
I'll say that the Campy ends and over-all "smell" of it seems like it's very plausible. And no "rifling" in that steerer that I can see so still might be Aelle tubing
But then this frameset has no familiar "smell" to me at all!
Maybe the OP will discover more clues as he strips all the paint (which he seems to be doing).
