Do you have a link? I'm not finding it easily and am not interested in buying it so I'm not willing to put much time into looking. But since I was one of the three people who built those frames, I might have some insight.

Edit: never mind, I just found it. It's the Real Thing, but it was a team frame (for the 1984 US Women's Cycling Team), not a production frame. Production 170s were all road frames; no track frames were built for non-team customers. The components are not be original (we would have send them out with a Campagnolo Pista group, not road pedals or Dura-Ace crank, for example), but are of appropriate era and quality.
