From what I can see of the craftsmanship there's nothing wrong with this frame. There's no chrome which sometimes connotes a lower-than-top-of-range model, the seatpost size (27.2 or smaller) could be another clue as to what tubing was used.
Another thing to check is if you see 5 spiral "rifled" ridges in the inside butt of the fork steerer.
