From what I've seen on this site, it was made by Giant in Tiawan in the 1980's. There is a good thread on the Schwinns of this era at "http://www.bikeforums.net/showthread.php?threadid=50844". I recently cleaned up a 1983 garage sale World Sport and it works better than I ever expected. It's a 10-speed with non-indexed Suntour gears and shifters, alloy crank arms and handle bar clamp but chromed steel seat post, hubs and rims. The bike has a lot of chrome and polished alloy which I think looks good but then I'm 61 years old so what do I know? I'm very pleased with the bike, especially considering it has only cost $30 so far, tires and all and is very shiny.
