The picture Carabela Semi-Pro does not have the Cinelli style seat cluster of the OP's frame. Still, I have seen this model with the Cinelli style seat cluster, so a Semi-Pro is a possibility. SunTour changed the Compe-V front derailleur circa 1977-1978, so the pictured Semi-Pro would appear to be earlier than that. Any chance you could post the serial number and date codes from the crankset and derailleurs.
