I just picked up this 84. Zukhan1 said it's a blue line edition. Was pretty dirty and when picked it up but I took it all apart today and did a major clean, still needs a few adjustments but it's pretty great so far.

Before clean up, really grimy





This is after a few hours of taking things apart, shining them up and putting back together. Everything cleaned up really nice, even the brake levers, has some scratching all over and the ends of the pedals are pretty banged up, but it seems pretty good for an old girl.
