Looks likely to be a Cinelli, final check would be 26.2 seatpost size. If it is a Cinelli it has been repainted and bottle bosses added on down tube and cable guides under the bottom bracket, there may be other braze ons I haven't noticed. It has an earlier Cinelli 1a nutted stem, and mixed of parts like Shimano brakes, later super record shift levers etc. The headset may be original. Although Cinelli serial numbers are all over the place the one on this bike has the ring of being correct. If you can see the head badge clearly there is a site somewhere which shows the different periods of badge.
