uh, no: the OP's frame might SAY "special professional" somewhere on it, but it's clearly NOT the same as those pictured in the link: he says NO pantographing (no piercings in lugs and I'd bet BB shell, too) plus the OP's has no chrome and Gipiemme long dropouts. If it was SL it wouls also use a 27.2 seatpost, not a 26.8. And that's NOT exactly what a Columbus SL decal says, which depending on the era looks like one of the pics attached.
I think the OP has it right: this is a mid-range Viner, not top-of-the-line, but also a probably fine "rider" so nothing to hang your head over...
