The Richard Cunningham designed Altron NFS was intended as a triathlon bicycle, which are very similar to time trial bicycles. However, the Altron NFS was not a full bore triathlon model, and you may be able to use it as a road frame. The oval down tube and tear drop fork blades which were characteristic of triathlon bicycles at one time, have now found their way into road frames. True triathlon bikes have steep seat angles, with many at 78 degrees. However, the Altron NFS used more relaxed angles, that are closer to a road frame.
However, there are a couple of concessions that may cause some concern. The top tube is relatively long compered to the seat tube.This was done to achieve a short head tube that permits a lower, more aerodynamic handleabar position. The other concern are the wheels. All the Altron NFS that I've seen have used the small, 650C wheels. They do have advantages of being stiffer, lighter and more aerodynamic, but may be harder to find. I suggest you try some triathlon forums, specialty shops or Ebay.
I had a 1991 Altron NFS and I'm also familiar with the 1992 model. Yours is closer to the 1992 model which used Tange Concept tubing. However, there are a couple of notable differences, so I wonder if yours could be 1993. It appears to lack the bottle mounts on the rear of the seat tube, the seat tube is not extended very much above the top tube and the seat post is secured using an aluminum clamp, as opposed to welded ears on the front of the seat tube.
FYI, the 1991 & 1992 Altron NFS both used Shimano Ultegra groups with Trispoke 650C wheels and Profile areo bars.
