To this end, I'd be doing a little closer examination of the frame, to determine if it might be a mid level model. What size seat post does it take? Is there any sign of a weld seam down the inside of the seat tube? If you have the fork, are there helical ridges inside the bottom of the steering column?
T-Mar,
The Treviso was Pinarello's value oriented mid line bike. Tubing during this period was Columbus Tretubi main triangle, stamped lugs and btm-bkt. The particular 1980 Treviso that I once owned featured a fully chromed ,Columbus SL fork with an investment cast crown and chromed Campagnolo rear dropouts with adjusters.Seatpost was a 27.2 and there were indeed 3 braze-on toptube brake cable guides.
