I think the Benotto is a slightly different kettle of fish from the Colnago. Aside from the bike refurbishing with less than original paint, and stickers ...oh, and yes the fork doesn't belong here, there is another thing which puzzles me and that is the cable routing on the top tube. Most pre-mexican 3000's I have seen had cable loops on the top tube and not internal routing. In the early 80's some Benotto 3000 models had internal routing but whether these were made in Italy is a question. Having said that many good frames were built in Mexico as well...not all broke. Still think this looks like a 3000...but then I have been wrong before.
