Is the tubing Columbus SLX on track frames. At least in road Paramounts it is. And is the seatpost 27.2?
Yes; I have the 1990 catalog that shows the geometry for the Paramount Classic (SLX tubing for smaller frames and SL tubing with SP down tube for larger frames) and the O.S. Road Frames (PDG/True Temper OS tubing).
According to the 1990 Parts & Accessories catalogs, the track frames that year were available as a custom option. That usually means the frame tubing and geometry would be specified by the customer. If the customer chose SLX, it would have a 27.2mm seatpost. If the customer specified PDG/True Temper OS tubing, it wold have taken a 27.4mm seatpost.
The best way to tell whether it's SLX or SL/SP, or PDG/True Temper OS is to measure the top tube and down tube diameters. If the top tube is 25.4mm and the down tube is 28.6mm, the tubing is Columbus SLX or SL/SP. If the top tube is 28.6mm and the down tube is 31.7mm, the tubing is PDG/True Temper OS.
For $50 Waterford will provide you with a provenance report telling you what you have.
