I have a (presumably) 1979 Schwinn, but when I got it, it had no stickers besides the 1020 steel sticker, and the xtra-lite bicycles sticker. I don't have a picture right now, cause I'm not on my computer, but if there's anyone that can tell me, I'll take super close ups of the frame.

Or better yet, does anyone know of a site where I can input the serial numbers and find out that way. I know it had four numbers on the badge. It's a Chicago Schwinn, for the win.

Thanks!
