I read what there is on "Velosport Bologna" in the CR archives and according to Listmaster Dale, if yours has Gipiemme dropouts it's likely from mid-to-late '70s.
Another owner of one of these "export prohibited" Italian-market-only bikes says his has no tubing decal...so I wonder if the foil Columbus decal is real or a wanna-be.
As far as price: the only 'for sale' was in 2004 for a frame/fork with HS and BB plus shifters in good/fair condition (original paint and decals): $125.
