Columbus XLX?

I've been offered an old track frame with Columbus XLX tubing but I have never heard of this type of tubing before and it isn't in that chart that creeps up on this forum, does anyone have any experience with this type of Columbus tubing? Thanks.

There was SLX and TSX but I don't remember XLX. SLX had the rifling inside at the butted ends; TSX had the rifling the full length of the tube. (The "T" was for Total.)

There was also SPX which was the heavier track or "Pista" tubeset.

There were six raised spiral ridges inside the tubes rather like the rifling in a gun barrell. These spiral ridges had always been in the Columbus steerer tube; in the mid to late 1980s Columbus brought out the SLX with the ridges in both ends of the top and down tubes, the bottom end of the seat tube, and also in the fat end of the chainstays. The idea was to make the tubing more resistant to twisting but make it lighter than the standard butted tube.
