If I had to guess, I'd say that those are DEFINATELY Asian bikes though-
They are a step above what I recall the Free Spirits were back in the '70's, but you have to realize that the japanese and asian quality really went up through the '80s as far as cycling equipment, so that when Campy got too expensive and exotic, they were ready to offer a great lower cost item on even the top end-
but at the consumer level, they just out-produced everybody else. All kinds of makers started incorporating more equipment and bikes into their lines. I was working at a shop in summers of '73 and '74. We had one line called "Italvega" which were almost exclusively italian manufactured- although I don't know if the name was worldwide or some kind of American distributor. But by the second year, the line had changed the name to "Univega", and began to sport more japanese equipment until I think it became pretty much all Asian.
Nice bikes.
