Generally we need more info. The world sport started kind of low in position, and gradually got better in quality.,,,,BD
My 85 World sport has a BB s/n of GO285.
I have an 84 World Sport and it seems to be better quality than this one. On this one, the components are; Shimanno SIS deraillerus & shifters F&R, Pro Star brakes & levers, Champion handlebars, Sakae SX crank set.
Found a sticker on the chainstay that says Schw App Giant 3506. Newer looking decals than my 84. The large SCHWINN decal on the seat tube is made up of lots of thin black lines also says World Sport on seat stays and top tube with lots of thin horizontal black lines after the words. Bike is a very bright red. SCHWINN is in black while World Sport is in white.
Camera is on the blink...
