The serial number indicates a 1982 model. As stated by Otis, the components suggest a mid-range racing model with a Tretubi frame. The components listed are a match for the 1983 Nuovo Racing and given that there is often little or no change between model years, a Nuovo Racing would appear to be the best candidate. FYI, the stays and forks on the 1983 Nuovo Racing were Falck, so there is a good chance it also have been used in 1982 as opposed to Columbus Zeta or Aelle.
